Bart, 
 
I have read your comments about the format of my reports.  I hope you will 
forgive my use of the existing format, while I consider how to respond to 
your comments. 
 
 
These two OBS of C* 2315 r seem to form a progression with the previous 
two:

I supply a conventional report for PPAS, recognizing that that is normal 
behavior for such an OBS as this.  However, it was not quite as free of 
unusual events as the timimgs might imply.  If you see analytic support for a 
synodic anomaly around 1h24m, I would be quite comfortable with such a 
conclusion.  But if not, I would readily accept that no such behavior was 
seen.  The next OBS, in contrast, seems to be a very typical, normal OBS.

PPAS: 
 
Walter I. Nissen, Jr., CDP, dk058@cleveland.freenet.edu, 55 Barrett RD #808, 
Berea, OH 44017-1657, USA, 216-243-4980, -81d 51.823', 41d 22.413', 256m, 7x35 
95-  8 B 96-04-18  1:14:11.6 WN  211.6 3.    6 35.3   M'M', C*2306r, mag 3or4 
 
Probing my 1000 elset file of bright objects, I find no candidate for the UnID 
I saw while timing C* 2315 r, except for C* 2219, the motion of which 
fits beautifully. 
So I feel I have no alternative but to provide this rather ludicrous report: 
92- 76 A 96-04-18  1:39      WN   12.  5.    1 12.    A'A', (UnID, C* 2219?) 
If this one wasn't C* 2219, then it had a very similar motion. 
 
88- 53 B 96-04-18  2:30:41.7 WN   19.1 1.    1 19.    A'A', C* 1954 r, mag 4? 
 
95- 32 B 96-04-21  1:19:41.4 WN  329.1  .5  25 13.16  A'A', C* 2315 r 
The shape of each maximum was a slow rise, followed by a sharp peak, followed 
by a rapid decline.  By the end of the OBS, the As were almost sharp enough to 
be Fs. 
 
95- 12 B 96-04-21  2:10:26.4 WN  128.6 5.    2 64.    M'M', C* 2310 r, 5?->6? 
95- 32 B 96-04-22  1:49:40.2 WN  134.4  .8  10 13.44  A'A', C* 2315 r 
 
 
Everyone,

This question has drawn no response.
