Last night about 8:45CST (2:45UT on 11/14/99), Ed Cannon found
object 99001 (with a little help from me) about 3 minutes early.
Observations were with my 8 inch telescope from the BCRC
site.  (30.3138N, 97.8661W)

Revised elset:
1 99001U          99317.30086492  .00000000  00000-0 +00000+0 0    02
2 99001  10.6240  39.3981 0035000  65.0440 294.9786   .98678900    06

When we first spotted it, the "main flash" was about 8th magnitude.
Preceding this main flash by about 4.0 seconds, there was a secondary
flash about 9th or 10th magnitude.

The flash period was measured at 21.395 seconds over a 28 minute
time span.  This compares to a 21.464 second period last January.

After about 5 minutes or so, the main flash was a little brighter,
the preceding flash was a little brighter, and a third flash appeared
about 3.5 seconds after the main flash.

After 25 minutes, all 3 flashes were brighter.  The main flash could
usually be seen in my 12x80 finder at about magnitude 7, the preceding
flash was about magnitude 8, and the following flash could sometimes
be seen in the finder at magnitude 7.5.

(PPAS obs sent to Kurt in a separate message.)
