Rubin Observatory First Look Watch Party 7
Heard about this? The first amazing and beautiful public images from the incredible new Rubin Observatory are coming soon, and First Look viewing parties are being organized for the initial release. Exact date is to be determined, but their estimate now is June or July. Also TBD is how they will manage display of the 3200 megapixel images. More info and sign up a local party here: https://rubinobservatory.org/news/rubin-first-look/rubin-party Roy

Boardwalk Astronomy 3
The Back Bay Amateur Astronomers (BBAA) in Virginia Beach, Virginia held our first of 2025 annual Boardwalk Astronomy yesterday afternoon and evening. I had a list of double stars to show tourists and locals alike but never had time to move the telescope away from the moon. Besides, we had numerous telescopes showing everything from the sun to Jupiter, a globular cluster and even a galaxy. It was challenging seeing the globular or the galaxy due to severe light pollution, but people were overwhelmed at everything else they saw.

Camera Concepts 4
This is fun link Hunter Outen did at this year's NEAF in NY. Huter was 15 or 16 when he and C.J. Wood used to come to ECSP. Thanks, Ray M for sending the link. I was fortunate to have Camera Concepts come to ECSP several years. Owner Jeff Norwood said it wasn't his biggest star party for sales, but it certainly was the most fun! Everyone has grown up now. Well, except for yours truly. Kent Blackwell https://youtu.be/iPuwqizwXA8?si=IwsbXRRXXx3tzHOL

Struve 1825 3
This is a pretty double, easy to find because it's next to Arcturus. I dragged out my old TMB 100/800 4" f/8 refractor, made by the late Thomas M. Back. Struve 1825 4.4" This lovely pair are only 1¡ã from Arcturus. The 6.4 magnitude primary is orange, and the tiny 8.4 magnitude secondary is blue. I haven¡¯t used the TMB 100/800 in a long time. Wow the optics are simply wonderful. I saw equal to fraction rings on both sides of focus. Absolutely no difference.

Double Stars
I was exhausted yesterday after cutting down a tree and pulling weeds, so I rolled out the 5" refractor for a quick observing session. I have a challenge. The star 35 Coma Berenices is a pretty double star, with a widely separated gold primary and a blue secondary. But wait, the 4th magnitude primary has a 7th magnitude companion only 1.2" apart, making it a triple star. See my notes below. Can you see the close pair, and if so, what telescope? I've seen it before at very high power with my TMB 100/800 (4"). I wonder if it can be done with as small as an 80mm refractor? List: 25/04/30 Takahashi TSA-120 Jupiter (Planet in Taurus) Observed: Apr 30, 2025 at 8:38:56 PM Comment: Using the 5mm Pentax at 180x and an 80A blue filter I was barely able to see the GRS as is heading towards the western limb.

The primary is pale yellow and the secondary is light blue Location: Virginia Beach SQM-L 17.4 75¡ã H 72% Equipment: 120mm F/7.5 Takahashi, 7mm Pentax Seeing: 9 Transparency: 8 35 Comae Berenices (Double Star in Coma Berenices) Observed: Apr 30, 2025 at 9:30:04 PM Comment: A beautiful gold primary and a blue secondary. SkySafari shows a 1.2" companion, but I could not see it. I saw it with this same telescope in 2021 using a Vixen HR 2.0mm at 450x. Taking my own advice, I tried the 2.0mm and sure enough I saw the tiny blue companion. Checking my notes again I've split this tight pair a dozen or so times before. The smallest telescope was my TMB 100/800 amd a Takahashi TSA-102, so I know a 4" refractor is capable.

BBAA May 2025 Update
Good evening, folks! May is (literally) just around the corner, so I wanted to share the month's news and heads-up! This week, we will have our monthly club meeting at TCC Virginia Beach's Science Building. We will be joined (by Zoom) by Dr. Charles Law, a NASA Hubble Fellowship Sagan Fellow at the Department of Astrophysics at the University of Virginia. Dr. Law will be sharing some of his work on astrochemistry, specifically in stellar and planetary formation. I hope you all share my enthusiasm in what promises to be a great topic! Upcoming Club and Outreach Events: - 1 May (7:30pm): Club Meeting at TCC Virginia Beach Science Building - 3 May (11:00am): Astronomy Day at the Churchland Library - 6 May (6:00pm): Boardwalk Astronomy #1 at near the 24th St Stage - 8 May (8:30pm): Garden Stars at Norfolk Botanical Gardens - 10 May (10am): Saturday SUNday at Elizabeth River Park - 16 May (8:00pm): Cornwatch at Cornland Park - 17 May (10:00am): Astronomy Day at Portsmouth Public Library - 17 May (8:00pm): Skywatch at Northwest River Park - 23 May (8:00pm): Cornwatch at Cornland Park - 24 May (8:00pm): Nightwatch at Chippokes State Park Upcoming Astronomical Events: - 6 May: Eta Aquariids peak, Saturn achieves equinox (with edge-on rings) - 15 May: Double Shadow Transit of Jupiter Between Saturday SUNday and the two Library Astronomy day events, it's a convenient time to have had so much solar activity. Let's hope it continues! Eyes up and clear skies! Jeremy

My comments for a short but fun observing session last night
Nothing special here - just thought I'd share that I got out last night and hoping to get out again tonight. No mosquitos and low humidity - a pretty enjoyable evening.

The Sun April 29, 2025 3
There's a huge sunspot on the eastern limb of the sun, so it'll be visible several days. There's surprisingly little difference in detail on the sun between these two telescopes. One is a bit easier to carry on cruises! Takahashi TOA 150 on an Astro-Physics mount vs Williams Optics MN 66mm on a Manfrotto BeeFree aluminum tripod. I've found aluminum has less vibration than carbon fiber.

YRSP: potential May date change - feedback requested 2
Our next scheduled YRSP date is Saturday Night, May 31st. That date does not work due to Ranger Staffing. I need feedback: we could move it to Friday Night, 30 May. Is Friday Night 30 May acceptable or should I completely cancel May? The previous [Memorial Day] weekend doesn't work and moving it a week later puts us a few days before Full Moon/SkyGlow. Post a reply here or message me directly, either is fine.

Huge Solar prominence today 4/27 3
Anyone with a H-Alpha scope. Look at the 6 o'clock position and you will see a huge looping prominence. I am attaching a cell phone photo that was taken through the Coronado PST.

Telescope and Mount Recommendation 10
The ranger (Austin) in North Carolina that we work for their annual statewide star party is interested in getting an entry level solar telescope. Does anyone have suggestions? Do you think this one is better than the Coronado PST? https://agenaastro.com/daystar-solar-scout-60-mm-solar-telescope.html If neither, can someone recommend one near the $1000 price point? I see High Point has a good selection but I'm not sure which is the best one to recommend to them. https://www.highpointscientific.com/shop?q=solar+telescope Does anyone know a good tracking mount to use with it? The club has the iOptron Cube and it works great. Unfortunately it has been discontinued or I would recommend it. I think they would rather have an easy to use tracking mount than manual but I am sure that Austin would be interested in any recommendations we can give him. Thank you!

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.
