This is a very red star, benefits our Watec cameras. The path essentially falls on top of Summit Rd, and Karl. The duration is only 0.2s, so it will require 2x setting to get enough points to be detectable. 0.2s = 10 fields for my PAL camera. So at 2x that would be 5 points inside the occultation, which should be detectable OK. The field is in Ophiuchus in the SE.

Alt=28, Az=154 in Ophiuchus, 12 degrees left of Antares

 

     

Kirk Bender's planned site: Glenwood Drive / Clark Drive just off Hwy 17. not far past the "Wedding Chapel" on Hwy 17.
My site: at the lot below the Red cafe at "Red Realty" site.

I got a recording at 2x from the old Red Cafe lot, in clear calm conditions. Visually it looked like a miss, but I've not reduced it yet

Looks like a miss or undetectable for 1996 TQ54, 2x at Glenwood dr. off hwy 17 June 4. Target was faint at 2x, but I didn't want to integrate longer because it was predicted to be short. There is a 2 point drop at 6:54:57, 2 sec earlier than the predicted 6:54:59, but there are other single and douple point drops thoughout. If asked to find an event, PyOTE finds a .2s event much later at 6:55:15 with a no confidence -0.0 sigma. If I trim near predicted time, it says no event found. PyOTE detectability tool reports an event as short as 0.340s would likely be detectable, 0.2s was max predicted. A miss or too short to be detected.

Looked like a miss but not reduced yet.
