Again saw all three objects from this recent launch tonight.
The payload, #24876, has multiple flashes (at least 2) per second.
Although not timed, I am apparently seeing flashes off of different
parts during the same revolution. Some are brighter than others.
The transfer rocket body, #24878, did nothing special. As it left
the field of view, I "thought" it may have dimmed, but since I did
not track it, it will be assumed to be imagined at this point.
These objects were seen about 03:17 and 03:14 UT, 25 Jul 97,
respectively.
The Delta II rocket body, #24877, was observed at 04:03 UT. Initially
it was faint in binocs but then brightened and faded. Then it brightened
in the south to easy naked eye visibility. Thus it "may" be tumbling
with a period of about two minutes. Or this may have been a phase
angle effect. I observed it for a longer period than last night so
this would not have been noticed last night.
Also observed #4813 in the telescope while waiting for GPS 2R-2.
Now waiting for good visibilities of Vanguard 1 to verify an earlier
obs in the 8" telescope.
Superbird A should be appearing again within a month I hope. Anyone
want to guess as to the flash time?
