This is an almost impossible event for our 8SE scopes. Word of this event was mailed out by a PhD student in Spain just hours before the event, when I had a medical appointment and then a 3 hr class to deliver, ending at 9pm. I had only 1 hr to get to Cabrillo Observatory and see if I could find it. It was not in OWc and so getting the information needed for charts was difficult.
I planned to hook the Watec up to the end of the 12" Scope in the Cabrillo Observatory dome, at f/6.3. However, the pointing for this scope must be done in the Gemini software, and it was not clear whether we needed to use Jnow or J2000 coordinates to input. The Gemini software uses its own catalogs and so this issue is not really dealt with. I quickly ran out of time, given the Astro 3-2 class ending just before the event. I did take a few images with the CCD ST2000xmc camera still attached and focused. But even 11s images only recorded stars to 14.3 magnitude, I found by aiming at M31 and using C2A. I got no data. I took a few pix at the Observatory, which may get posted in the table below at some point.
Observed from Bonny Doon with the 8SE at f/3.3. PyOTE found a 4.2709s event in my recording for the TNO 2010 SS43, at 128x from the Bonny Doon Eco Reserve on Sep. 22. I was pleasantly surprised, given the faintness of the target (G = 16.54) and the path uncertainty, but PyOTE's NIE test gave a sigma distance of 8.3. I used a static mask of size 2.4 in PyMovie. The target is visible in a finder frame from PyMovie, it matches the DSS charts on the Occultation Portal. I don't know what exactly the predicted time was for my location, but we were told the observing window for the west coast was from 05:07 UT to 05:15 UT, so that is when I recorded, and I have the vertical line in the PyOTE and PyMovie graphs at the center, 05:11:00. The event PyOTE found was centered on 05:11:09.1734. The event is not in Occult Watcher, but I have uploaded my data including dark and flat recordings to the Occultation portal at https://occultation.trgozlemevleri.gov.tr/

So far, 6 stations are listed on the portal, there is one other positive than mine, at the Sierra Nevada observatory in Spain, on a 1.5 meter (60 inch!) telescope with 2 sec. exposures. There are 2 negatives, 1 technical failure and another not reported. The positive in Spain is apparently, from the map, on a similar chord to mine so we would seem to confirm each other. It doesn't say what the time or duration of the other positive is.
