Image Details:

On November 21, 2023, I observed the occultation of TYC 1236-00841-1 by Uranus' largest moon Titania remotely using two 0.61-m f/6.5 telescopes located in the east and west of North America: Burke-Gaffney Observatory (BGO) in Halifax, Nova Scotia, Canada (MPC code 851), and iTelescope.Net T24 in Sierra Remote Observatory at Auberry, California, USA (MPC code U69).

The exposures were 1 second for each frame, but in the first case there was a break (interruption) of about 8 seconds between images, and in the second - of about 15 seconds, so I determined the occultation time (UT) with the corresponding errors:

For the BGO: start: 05:15:59.4 +/- 4 sec.; end: 05:17:03.4 +/- 4 sec. (first light curve);

For T24: start: 05:19:21.2 +/- 7.5 sec.; end: 05:20:34.8 +/- 7 sec. (second light curve).

Titania has no dense atmosphere, so the occultation was instantly.
