Kirk and I were a bit less than an asteroid radius apart.
This is a short, difficult event, but convenient in time and place in the sky. We could get lucky and it may look bright enough to get a detectable and solid event. Kirk's on the northern limit, I'm barely inside the 1-sigma zone. We'll try it from home

I got a recording at 8x. Noisy, as expected for this faint target at short integration. I see no evidence of an occultation, and likely a miss.

A full duration event should show in the data, but there's no hint. The best interpretation is that we had a north shift, enough to get Kirk near the centerline, but barely a miss for me, still consistent with a round asteroid. |
I got a .4 sec event for 2002 VR101, 8x from home, but the best I could get on the NIE test is between 3 and 4 sigma. First I tried several static mask apertures, they all failed 3 sigma. Then I tried the same but with appsum values instead of signal, and only one of them barely passed 3 sigma. Then I tried a TME aperture, signal failed 3 sigma but appsum passed 3 sigma better than the static appsum, so that's what I'll report.

Looks like a positive; brief, at the right time. |
