I agree with this. The "irregular" second Mm cycle also seems to change as the object traverses the sky, particularly on a passage with a high azimuth, being better defined at high Az. angles. I've not been observing "flashers" long so YMMV. pj -----Original Message----- From: Michel Jacquesson <Michel.Jacquesson@wanadoo.fr> To: SeeSat List <SeeSat-L@blackadder.lmsal.com> Date: Tuesday, September 14, 1999 9:19 PM Subject: Double pattern for Okean-O R/B Hello everybody! Okean-O R/B (25861,99039B) seems to have a changing pattern : the first is a common one (A'A') with a short period (last record = 0.676 sec on Sept 10) and sometimes a more sophisticated one (-'MmM-') that is a constant bright aspect, interrupted alternatively by a very short period of diappearance and a short period of minimum. Here are my observations in PPAS format : 99- 39 B 99-07-26 20:52 MJ 52.6 0.1 100 0.526 F'F' after culm 99- 39 B 99-07-26 20:52 MJ 53.8 0.1 100 0.538 F'F' before culm 99- 39 B 99-07-30 21:02 MJ 56.3 0.1 100 0.563 F'F' 99- 39 B 99-08-03 21:15 MJ 56.9 0.1 100 0.569 A'A' before culm 99- 39 B 99-08-03 21:15 MJ 57.5 0.1 100 0.575 A'A' after culm 99- 39 B 99-08-21 21:17 MJ 60.6 0.1 200 0.606 A'A' 99- 39 B 99-08-26 20:17 MJ 249.4 0.1 200 1.247 M-'MmM-' 99- 39 B 99-08-30 20:29 MJ 127.2 0.1 100 1.272 -'MmM-' 99- 39 B 99-09-02 20:13 MJ 63.9 0.1 100 0.639 F'F' 99- 39 B 99-09-06 20:25 MJ 66.3 0.1 100 0.663 F'F' 99- 39 B 99-09-08 19:42 MJ 265.7 0.1 200 1.328 -'MmM-' 99- 39 B 99-09-10 20:35 MJ 67.6 0.1 100 0.676 A'A' What seems curious is that either one pattern can appear or the other one, without apparent regularity. Perhaps somebody has seen this aspect? -- Michel JACQUESSON 4°05' E 49°36' N
