My second station for 2000 QR4 Sunday evening produced a very noisy miss.? When I ran it through the PyOTE detectability tool, I found that it was detectable for a 0.27 second or longer event, not detectable for shorter.? Following the PyOTE instructions, I'm to report a qualified miss, with a negative for 0.27 or longer and a no observation for shorter (predicted maximum was 0.3 seconds, and my home station had a 0.38 second positive).? My primary question is how do we report this on the Excel form?? The pulldown options are Positive, Negative, and Unsure.? There is no Qualified Negative.
?
It is fairly rare that I report misses (I only do this on ones that have a positive, either from one of you or a second station of mine)--is this analysis something you all run on each reported miss?? Somewhere along the line I missed having to do this.? If this is standard, I guess I will need to do it for the other miss I had Sunday night and update the form I already submitted for that one.
?
Thanks.

Wow...? excellent job Elizabeth!? The poster is looking good.
The one update I have.. is that we do not have students working with occultations at Ryan, Grassland,? nor Naylor observatories.
With the current title, I don't want to give the impression that local observatories are not welcomed unless they have students involved..?
Does anyone have title or comment suggestions for helping to fill the "white space" ?? - Roxanne

Hello,

NOW is the time to tell me what else you want on the poster! There is some room at the top to add some general text. As you can see, most of the text boxes have some room as well. We might be able to squeeze in a few more pics of facilities, but really, try to get pics that have students in them. Anyone can go to the websites to see the facilities. I had thought it might be good to have what size aperture(s) is being used by the facility, but since I didn't have the info for anyone else, I took it out for UMD.
I will be sending the final draft to Roxanne this weekend so that she can print it in time.

Steve, that is a very interesting plot of 199JY123.? OccultWatcher indicates that it is a main belt asteroid. As such I was expecting relatively straight line and generic D&R drops.?? However, the light curve looks very similar to what we experienced with Pluto, as we observed the star's light pass through Pluto's atmosphere. There is more of a slope to the D line/edge along with a center spike to the data, but with a straight R line/edge.?
Curiosity speaking and in tossing out a few thoughts for group discussion... it is highly doubtful that we have an atmospheric influence on the data (like Pluto's data) Nix that chain of thought.? So... without a known size / diameter of the rock, could we be looking at a uniquely shaped asteroid? Large rock on one side, narrow "waisted" (hence the center spike to the data) with an attached secondary smaller rock, similar to Arrokoth?? - Roxanne

Re: Bright Occultation Sunday Night
Here's my preliminary results:
?
(9667) Amastrinc:? despite a fairly good forecast, it was cloudy all night
?
(32289) 2000 QR4:? had a -0.3 second event at my observatory on autopilot, the C-5/Astrid station needs more analysis but may end up being a no-result as the target was so faint
?
(56376) JY 123:? had a miss from the centerline with the C-5/Astrid and a neat looking positive from about 1.5 km north of there.? For the positive I used a 66mm refractor/QHY174GPS and ran at 100 frames per second (windowed and binned--only had one reported dropped frame).? That looks interesting, with a gradual drop on the D and a sharp recovery on the R.

Hi Folks,
I'm trying to work on the poster, but need input. I've taken the text Roxanne sent and put info into a spreadsheet. All material/drafts are in
I've tried to make it as open as possible but I may have to add folks more directly. Please email me warnerem@... directly if you have problems.
Please fill in the spreadsheet... if you have mentored students, please provide what info you can.
If you have photos of the students observing or lightcurves of their events, please upload them (Your last name_facility_event) or email them to me.
My aim is to have a poster that is mostly images rather than words -- a map of the NE US with lines from location to bubbles containing student image/LC and brief text...

Bright Occultation Sunday Night
?
It has been a couple of weeks since I had clear weather, an open schedule, and good events to try.? Tonight and Sunday night are looking partly cloudy and clear respectively here in Northcentral PA.? I have three near 100% events to try.? The first is pretty faint and at ~5:30 AM local Sunday morning--so that will be a single chord try from the home observatory.
?
The first of two Sunday evening is pretty routine.? I'm hoping to use the home observatory and the C-5/Astrid to get two chords --that will be a stretch for the Astrid at mag 12.6.? It is also just after it gets completely dark (~9:30 PM), so I'll be sprinting to get everything set-up on time.
?
The second Sunday night is the interesting one.? It would be the brightest occultation I've tried to record at mag 6.3.? It goes through a recreational area at a local lake about 10 miles from here.? This one has zero chance from home.?
?
For that one I need to decide if I'm doing a single chord with the C-5/Astrid or add in my 66 mm refractor and Watec camera to try to get two.? I'm a bit worried about way over-saturating the Astrid, so I'm going to do a test run tonight if clear.? I'm also thinking to running it fast (20 Hz?) since it is a short event (0.4 sec max)--even with my "bad" memory stick, I don't think I've had any dropped frames to date.

Re: Poster input for NEAF- Northeast outreach occultation activities
Well, we will have a couple of smaller scopes with cameras on hand in the booth. Plus, we typically have a plethora of posters showing various occultation set-ups.? So, don't think that people will lock into having to use a large scope. But, if there is room to indicate aperture size on the local observatory poster... that might help show a new use for some of the larger aging lonely scopes out there.? - Roxanne

Re: Poster input for NEAF- Northeast outreach occultation activities
Folder created
You should be able to put pictures in this folder. Whether one image or several, please have location at the beginning of the file name so that they stay sorted together. For example, UMD-student.png, UMD-Joensuu-lc.png?
There is also a poster there (sized 36"x24")... I think pics of students collecting/analyzing occultation data...
Going with Roxanne's idea of trying to highlight student work, my rough idea (and I could use some help) is to have a background map of the mid-Atlantic-NE US with lines from respective locations to a bubble showing a pic or collage of pics with info about what students have observed from that location.
Clear Skies! Elizabeth 301-405-6555
I can give this a go...
What final size do you want?
I'll make a Google Drive location where folks can deliver images, etc for the poster... And we can draft a poster collaboratively.
But folks can also email me files as well ...
