Wednesday evening, given an unexpected respite from cloud cover, from UT
Austin campus near my office (~30.29N, 97.74W) I was looking for a very
good (76 deg. culmination) pass of Lacrosse 2 (91-17A, 21147). Just a
few seconds after it appeared (~~1:52:47 UT Thursday 10 April) at azimuth
346 and altitude 31, it brightened to approximately magnitude -2 and
stayed there for about 1.0 to 2.0 seconds. Then it dropped back to
predicted mags. The total length of the flare was 3 or 4 seconds. After
that it continued to be a great pass of about 5 minutes, much of it
brighter than magnitude 2.0. (I can't confirm the exact times because I
had only my analog watch.)
About 10 minutes earlier, Cosmos 2326 (95-71A, 23748) made a very good
pass, 79 deg. culmination, as well.
And in the west was Hale-Bopp just below Algol (beta Pers) and north of
the 36-hour-old Moon.

[Yes, but I was looking for a term that would express the idea of
[observing without magnification and would be equally applicable to
[naked-eye and glasses-wearing observers. How about "one-power...?"]
