I have not kept up-to-date with recent observations made, by finding the RA/dec of the observed flash timings. If my model for Nov.10-16 flash holds, Ed's initial flashes Dec.1 and 2 came from a surface 90.0 degrees from "my" axis. This matches the majority of old observations, of which Ed's cover six sections of a circle, with only one large gap (about 7h of RA) Only the Nov.2003 series matches the 86-degree surface matching the Nov.10-16 observations. Ed: Do the (times and ) RA of your recent obs form a smooth series with your earlier Nov.obs, or do you find jumps? However, for Ed's Dec.1-2 start obs I find declination -13.2 and RA 22:05/22:01 I don't know the location of Orange County, or if Irvine is there, but if you can see Telstar 401 near declination -13.2, you should have flashes near RA 21:55 tonight. This seems to be OK for Irvine. But if you are at a different latitude, the changes are substantial. Now/there I401 moves hardly at all in declination, so 4 degrees of latitude can move the flash 0.5 degrees up or down, thus several hours of RA/time, or make them almost invisible. I401 rotation axis is close to the poles. Superbird-A has it near the equator, so its flashes move mainly in declination, so the intersection with the track is nearly at the same RA for all observers. /Björn ----- Original Message ----- From: "Ed Cannon" > Mark Hanning-Lee asked: > >> When should I look from Orange County, California, to >> see Telstar 401 flashing? > > I expect the first one-power flash here to be at about > 0:59 UTC ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
