Observations from San Pedro Martir Observatory (SPMO) confirmed a
quick R flash. It was seen visually by the telescope operator through
the finder telescope as a flash off of one of the satellites (he
didn't identify which one) through a 6" reflector. An observer at the
.84m doing photometry saw a flash 2 minutes after the predicted time
on the SE limb of Jupiter. Observations with the NICMOS Camila camera
at 2.2 um confirmed a flash about 15 minutes after the predicted time,
approximately Jul 22 22:45.
In the IR at 2.12 um the flash was a very quick brightening, a matter of minutes--the exact times are difficult to determine due to the closeness of the G spot. It also faded rapidly--again in just a few minutes. Since the signal was much lower than the L flash reported yesterday, it is more difficult to pin down the times more reliablly wihtout further reduction (and you know how much I hate instant science...). At 2.12 um, it brightened to a flux greater than Io for a brief time.
