Solar Storm
If your TV has been messing up or your Roku has been pixillating, it may be due to a current solar storm. Here is the news from spaceweather.com GEOMAGNETIC STORM WATCH (G2): Moderate (G2) geomagnetic storms are possible on April 22-23 when a co-rotating interaction region (CIR) is expected to hit Earth's magnetic field. CIRs are transition zones between fast- and slow-moving streams of solar wind; they contain enhanced magnetic fields akin to those of CMEs. Sky watchers across Canada and northern-tier US states from New York to Washington should be alert for auroras. Aurora alerts: SMS Text. A LARGE HOLE IN THE SUN'S ATMOSPHERE: A large hole in the sun's atmosphere is facing Earth and spewing a stream of fast-moving solar wind directly toward our planet. NASA's Solar Dynamics Observatory photographed the opening, which stretches almost a million kilometers across the sun's southern hemisphere: This is a "coronal hole"--a vast region in the sun's atmosphere where magnetic fields have opened up, allowing solar wind to escape. The hole looks dark because hot gas normally contained there is missing. It's on its way to Earth. At the top of the page, we predicted a CIR (co-rotating interaction region) would hit Earth on on April 22nd. This giant hole is the driving force behind it. Fast solar wind flowing from the hole is compressing slower-moving solar wind in front of it, creating CME-like shock waves and magnetic fields that comprise the CIR. G2-class geomagnetic storms are likely when the CIR reaches Earth. Sign up for Space Weather Alerts to receive an instant text message when the storm begins.

NWRP Saturday April 19, 2025 5
Despite a rather gloomy outlook the sky cleared for the BBAA Skywatch at Northwest River Park Saturday, April 19. It was good to see so many friends and be able to observe at least a few deep sky objects. Here are a few I observed with my trusty Orion 10" Dobsonian. List: 24/04/19 NWRP Orion 10" Ptly To Mostly Cloudy Messier 35 (Open Cluster in Gemini) Observed: Apr 19, 2025 at 8:36:48 PM Comment: Beautiful open cluster, with a myriad of stars in this cluster. I switched to lower power for an even better view. This looked great in William Kiff's 8" Celestron SCT at low power as well. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 3 (Globular Cluster in Canes Venatici) Observed: Apr 19, 2025 at 8:45:03 PM Comment: David Wright suggested this beautiful globular. Easily resolved, especially at the edges. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Black Eye Galaxy - M 64 (Spiral Galaxy in Coma Berenices) Observed: Apr 19, 2025 at 8:48:57 PM Comment: A large, elongated galaxy, with a much brighter core. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Needle Galaxy - NGC 4565 (Spiral Galaxy in Coma Berenices) Observed: Apr 19, 2025 at 8:56:18 PM Comment: Very low surface brightness, especially on this hazy night. This is normally a spectacular galaxy, but not when viewed under thick, hazy skies. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Sunflower Galaxy - M 63 (Spiral Galaxy in Canes Venatici) Observed: Apr 19, 2025 at 8:57:49 PM Comment: Round galaxy next to a fairly bright star. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 66 (Spiral Galaxy in Leo) Observed: Apr 19, 2025 at 9:01:09 PM Comment: The brightest of the Leo Triplet Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 65 (Spiral Galaxy in Leo) Observed: Apr 19, 2025 at 9:01:35 PM Comment: Only slightly fainter than M 66, therefore the second brightest in the Leo Triplet. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 NGC 3628 (Spiral Galaxy in Leo) Observed: Apr 19, 2025 at 9:02:56 PM Comment: Very low surface brightness, highly elongated, and by far the faintest of the Leo Triplet. I had to use the old trick of rocking the scope back and forth to see it. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 95 (Spiral Galaxy in Leo) Observed: Apr 19, 2025 at 9:07:33 PM Comment: More elongated than nearby M96, but lower surface brightness Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 96 (Spiral Galaxy in Leo) Observed: Apr 19, 2025 at 9:08:10 PM Comment: Fairly bright galaxy with high surface brightness. Brighter than nearby M 95. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Messier 105 (Elliptical Galaxy in Leo) Observed: Apr 19, 2025 at 9:10:20 PM Comment: Small, 9.3 magnitude galaxy but with high surface brightness Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency: 6 Ghost of Jupiter Nebula - NGC 3242 (Planetary Nebula in Hydra) Observed: Apr 19, 2025 at 9:17:02 PM Comment: This is one of my favorite planetary nebulae, and it holds magnification well. I was barely able to see the CBS Eye. I looked at it in Jeremy Mitchell 12" Celestron Dobsonian but hazy skies knocked the brightness down considerably. Location: Virginia Beach, VA, User Defined Equipment: 10" Orion IntelliScope f/4.6, 10mm Pentax Seeing: 9 Transparency:

YRSP Tonight: cancelled
Upper-level particulates are increasing, we have some smoke moving in and a frontal boundary nearby. Clear [enough] skies are slim and I don't think anyone was coming anyway so I'm pulling the plug. When I set the dates in December, my Apple Calendar (or was it Google that I used?) didn't indicate the Holiday and I chose this weekend b/c I postulated the ECSP would be next weekend to avoid the SRSP conflict. IF there's interest, I can see if we can move tonight's date two Saturdays from now (FQ Moon), otherwise we'll go with our already set May date. Message me directly offline. There is a night hike tonight. If by chance the sky is 'doable', I will try to run over with my BinoTelescope and maybe a parallelogram with 25x100s since I live close-by. Happy Easter, Troy

This Saturday: YRSP attendance 3
Greetings, Saturday Night's forecast is iffy - strong southwest flow ahead of a warm front usually indicates high clouds (see attached). If we have clear skies, given the Holiday Weekend can I get a head count of who plans to attend? Cheers,

Star Adventure Eq Base for Seestar Locking Bolt
I recently purchased a Sky Watcher Star Adventure Latitude Eq base for my S50. Found that during mounting the knob that secures the dovetail is too big. After some trial and error, I found that an M8 machine screw fits perfectly and secures the dovetail.

Space Weather Today ¨C Uh-oh
Comet Swan is in trouble it seems ¨C lost its tail! May not make it through perihelion. And it seems my area is in trouble too ¨C recent extreme solar storms have caused geomagnetic ground currents through the Appalachians area that are 70 times normal! This may cause power outages, similar to the Great Quebec Blackout of March 13, 1989. No comment on what else that causes ¨C higher electric bills?

Free Astrophysics Talk at Virginia Living Museum - 4/17 (6:00pm-7:30pm)
Evening, folks! Apologies for the late breaking news, but for anyone who wasn't aware and is interested, the Virginia Living Museum is hosting part of their "Naturally Speaking" series, with Dr. Michael Rutkowski (Assistant Professor of Astronomy at Minnesota State University) for "A Casual Review of the First Century of Astrophysics - Where We've Come From and Where We're Going." Register for this free event here: https://thevlm.org/events/museum-events/calendar/events/naturally-speaking-dr-michael-rutkowski-the-first-century-of-astrophysics/ Summary: Astronomy is arguably the ¡°first science¡±, but inchoate astrophysics deserves the credit for fundamentally transforming humanity¡¯s understanding of the natural world. Over the last century, the history, shape, and composition of the universe has been revealed in surprising, remarkable ways. Over the past few decades, the application of some of the most complex, powerful scientific instruments ever constructed have dramatically accelerated these discoveries. In this lecture, I will introduce fundamental (coincidentally, within a Virginia context) concepts in astrophysics, including a brief review of some major revolutions in our understanding of the universe. Following this gentle introduction, the audience will then be able to appreciate some of the technical insights I have derived with large collaborations using ultraviolet and near IR space-based observations like the Hubble and James Webb space telescopes. Specifically, we¡¯ll discuss the curious formation and evolution of massive galaxies in the universe and the impact of the smallest galaxies on the cosmic evolution of elements. We will then focus on two topics, looking towards the future. First, we review the launch of new astrophysical observatories and their potential to fundamentally transform our understanding of the nature of the universe. Second, we discuss the application of machine-learning techniques to support new discoveries in astrophysics. Hope to see some of you there! Clear skies! Jeremy

Sad news from solar eclipse guru Fred Espenak 6
I just read this from Fred Espenak. Fred is and always will be regarded as the authority of eclipses, both lunar and solar. I have all his books and guides. Dear Friends. I want to share some sad news. I was diagnosed with Idiopathic Pulmonary Fibrosis (IPF) five years ago. I did not have any significant symptoms until last year. That changed dramatically in 2025 and my health has rapidly deteriorated. I have spent the last two weeks in a Phoenix hospital undergoing exhaustive testing to determine whether I am a candidate for a lung transplant. Unfortunately, my IPF has progressed too far for a transplant. I expect to be placed into hospice care tomorrow and will probably be gone within a few days or less. But I cannot complain. I have had a marvelous life of eclipses, astronomy, a NASA career, and my wonderful wife Pat, the greatest love of my life. I wish those I leave behind many more years of clear eclipses and awe for the heavens. Farewell to all of you,

Saturday Night: YRSP outreach & open observing session
Our monthly scheduled outreach & open observing session at York River State Park is this Saturday Night. The extended forecast isn't great but we're still 5-days & nights out. Calendar Note: if there is another event on the VPAS or Back Bay calendars, this is an additional event and it does not supersede nor replace any other event. Address: 9801 York River Park Rd, Williamsburg, VA 23188 Park Phone: 757-566-3036 Lat: 37.414639 Long: -76.713562 GPS Coordinates: 37¡ã 24' 52.7004'' N 76¡ã 42' 48.8232'' W The public is invited & this event is posted on the YRSP Website calendar & their Facebook page. We ask that members of the public who are attending to please park in designated visitor parking & walk to the site so there is enough space for the amateur astronomers to transport & park next to their gear on the observing field. After outreach, the amateur astronomers take over and we have YRSP to ourselves as long as we wish to observe. The sky at YRSP is as dark as it can get in this area. Important: the gate will be dummy-locked by the departing duty Ranger. If anyone leaves early, you¡¯ll have to open the gate, close it and (re)dummy-lock it (please do not lock the rest of us in). Observing Site (see attached map): After entering the park (the entrance fee is waived for amateur astronomers), the participating amateur astronomers should drive to & enter the ¡®right¡¯ parking lot. At the back/riverside corner of the lot, take the ¡°No Admittance¡± gravel road/path (we are allowed to drive on it) to the observing site where you may park & unload. If you notice public outreach attendees driving to the observing site, please help me police the area by re-directing them to the visitor parking lots. Due to the proximity of the river, be prepared to battle dew in any season. Consider bringing a lightweight tarp to cover your eyepieces and other accessories on your observing table. Those who have scopes susceptible to dew, you will likely need a dew heater. We¡¯ll start at sunset ¨C click here for YRSP sunset/sunrise times - and observe until we get tired. Forecast Links: Astrospheric CSC NWS A Go/No Go will be posted on the VPAS & Back Bay Groups on Saturday AFTN NLT (no later than) 3:00 PM. Hopefully the weather cooperates - and the tree pollen subsides. Cheers,

The moon at the public event
Mare Humorum was prominent Wednesday night for the public event. That is the circular dark Mare so prominent to the naked eye when the moon is approaching full phase. That would be 11.08 days of the lunation (days from the new moon). Humorum is a text book for basin formation and lunar forms. It is circular and though it is a bit more subtle that Imbrium or Crisium, Humorum has all the important features of a multi ring impact basin. It is circular first off and the first ring of the impact basin is the dark mare material itself. Other rings are a bit harder to distinguish but remnants are there. There are three craters on the edge of the mare forming a triangle. Gassendi in the north, Doppelmayer in the south west, and Hippalus in the east. Notice that they all have something in common. The crater walls facing radially inward to the basin center are all low and flooded. The outward walls, facing out, are higher above the surface. Each crater has a flat flooded floor of lava. Around the edge of the mare are what appears to be cracks or linear features concentric to the circumference of the mare. These combined, suggest that the weight of the overlying lava depressed the center of the basin into the softer mantle of the moon. As the center sank, lava poured in to the low spots in the crater walls, flooding the floors of the three craters. These lava were quite thin, about the viscosity of motor oil to cover so much ground. Cracks and ridges formed at the edge in response to the sinking of the mare. Crater density in the mare clearly shows it is of younger age than the heavily cratered surrounding bright highlands. It is often wrongly assumed that the mantle of the earth and moon are molten and very soft. That is not really correct in the short time. Examined, it would look quite solid. But over time it does flow (long time). A great way to visualize this is to take a stick of butter and bridge it across two plates at the ends of the stick. Initially it seems stiff and non flexible (unless you break it) but leave it there for a day and see what happens over a time period. Gravity will start to deform the butter into a u shape over time. Slow steady force over time is the key point to deformation. same for planetary crusts. Humorum is a good example of an interesting observation that is more than just a pretty impression.

Norm Sperling 3
I just watched an interesting, but L-O-N-G YouTube about Norm Sperling. Back in the early 70's he visited the Chesapeake Planetarium. I invited Norm to come look through my 8" f/8 Optical Craftsman telescope, a telescope I have always regretting selling. Gosh, I'd like to have that scope back. I think Dick Nelson, owner of The Optical Craftsman made the mirror. Norm and I spent most of the night stargazing in my backyard in Chesapeake. Anyway, back to the YouTube. I never knew later on Norm invented a telescope which became what is possibly the biggest selling telescope of all times, the Edmund Astroscan. For those youngsters who've never heard of it, Google Edmund Astroscan. Kent Blackwell

Herschel Objects 15
A few years ago, I completed my decades-long project to observe the objects discovered by William Herschel. As part of that effort, I compiled the attached spreadsheet that contains extensive data on the Herschel objects. It occurs to me that it may be of interest to some on this list. It took considerable effort to compile and I¡¯d be pleased if someone can make use of it. The information comes from a number of sources including the websites of Wolfgang Steinicke, Harold Corwin, and Steve Gottlieb as well as Greg Crinklaw¡¯s Sky Tools program. Any errors are mine. Below is a description of what is contained in the spreadsheet: Tab: LIST contains data for 2,517 objects that William Herschel discovered or independently found, including descriptions. Tab: Non-Existent lists the 106 or so Herschel objects that the NGC lists as non-existent with explanations for that designation and current status based on the research of Steinicke, Corwin, and Gottlieb, and a few others. Tab: Steinicke Add are the objects not generally attributed to Herschel that probably should be included based on the research of Wolfgang Steinicke. Tab: Stars are those supposedly nebulous Herschel objects that are just stars. Tab: Discovery lists the discovery date referenced to the Herschel catalog and NGC designations Tab: Notes contains information on the Herschel catalogs and object classifications and several other pertinent data such as the original discovery data (for objects for which Herschel does not have primacy). It also contains some extensive notes (Steve Gottlieb¡¯s summaries) for Herschel discovered objects without Herschel designations. There are also statistical summaries and notes on duplications and other anomalies in the catalogs. Tab: Abbreviations lists the standard NGC/IC abbreviations used for the object descriptions in the spreadsheet. Tab: A.L. List is the data on the 2,381 (now 2,379) objects that the Astronomical League recognizes as legitimate Herschel objects for their Herschel Society certificates. The objects in the ¡°Herschel 400¡± and ¡°Herschel II¡± are identified as are the 74 objects discovered in a single night (April 11, 1785) that constitute the ¡°Herschel Hustle¡±. I logged my first Herschel object on February 3, 1992 using an 8-inch SCT from Virginia Beach, VA, and the last one on March 30, 2019 with my 30-inch from my observatory outside of Sierra Vista AZ. The 27-year span is misleading as it really didn¡¯t become a goal to observe the whole list until about 2015 or so. It was actually a consequence of my larger (still ongoing) effort to view all the NGC and IC objects visible from my home observatory. Ted Forte Herschel 400 Program certificate #298 June 4, 2004 (400 objects) Herschel II Program certificate #48 September 25, 2006 (400 additional objects) Herschel Society Silver Certificate August, 26, 2018 (1,200 objects total) Herschel Society Gold Certificate April 9, 2019 (2,379 objects total)
