I have received a second observation report, this time from an observer in Western Canada. He did not indicate whether or not he wishes to remain anonymous, so for now, I will only provide his coordinates and obs report. Start of report: 4 Jul 96 GMT 1st object, bright flashes to zero mag, down to invisibility (but in modestly twilight-lit sky still) 18h 00m +89deg 25m (2000.0) 5h 22m 17.4s GMT 2nd object, glints to 1st mag, down to perhaps 3rd, violet color tinge (reminded me of the Lacrosses) 20h 40m +89d 40m (2000.0) 5h 23m 56.3s GMT observing location 51.040N 114.078W elev 3450 ft End of report: He was using the 57 deg elset I issued last night, however, the object was about 11 min early. Given that his obs was only 2 rev after that of the Ohio observer, whose obs seemed to fit well with the 15 rev/d mean motion, I soon realized that the mean motion had to be closer to 16 rev/d. I found that 15.9 rev/d works well, within the precision of the obs. The Ohio report was measured only to the nearest minute; the Canadian report was measured to a fraction of a second. By moving the RAAN about 8 further east, I could force the 57 deg inclination to fit the obs, however, that would have required much more of a dog-leg by the Titan than I can believe. Using the 55.2 deg inclination implied by the announced launch azimuth of 40.5 works very well with the launch circumstances and both observations. So the greatly revised orbits are: 99600A 10.0 3.0 0.0 5.0 1 99600U 99600 A 96185.02152778 .00000000 00000-0 00000-0 0 02 2 99600 55.2000 188.0000 0000001 0.0000 49.7000 15.84300000 07 99600A r 9.8 3.0 0.0 5.0 1 99601U 99600 B 96185.02152778 .00000000 00000-0 00000-0 0 03 2 99601 55.2000 188.0000 0000001 0.0000 31.2000 15.90000000 08 The payload trailed by about 1 minute for the Ohio observer, and 1.65 minutes for the Canada observer. This suggests a mean motion of about 15.843 for the payload, as in the above elements; however, the Ohio obs was stated only to 1 min precision; therefore, there is considerable uncertainty in the mean motion. It is interesting that both observers report that the payload is reddish in colour. Often when I observed SDS 2-1 (89061B)I noticed a very subtle red/orange hue; however, no other observer agreed with me on that. The fact that both observers report colour may actually point away from SDS as the identity of the new payload. Perhaps a precise flash timing would help settle the question. The payload can be expected to make a major manoeuvre at any time, so it is very important to track it at each opportunity. I was clouded out again last night, but it is clear now, and I am optimistic about tonight. bye for now
