Timings: Jul 3, 2004 UT



Comments: The 11.9 star is barely visible above the noise on the playback. Absolute limiting magnitude was perhaps 12.1. The star was actually invisible at the time of the recording. I blind positioned using the LX200 go-to feature after testing gave good confidence that the star was in fact on the frame. I shielded the telescope from the strong 20mph wind using the backdoor of my Toyota RAV4 SUV, and this did a pretty good job. Still, some small jitter and wandering did occur, but was not a major problem. The event lasted only about a second, and timings will await a light curve courtesy of Frank Anet.
