The satellite is generally not observable between flashes, so scan slowly if you're out looking for it. I do not have a good orbit determination program or the skill to do an orbit fit myself. Please note that the checksum on line 2 is probably in error. I arrived at the Mean Motion by plotting the moment when the satellite crossed the -4 degree Declination line on two consecutive nights. However, this did not match the observed path exactly for some reason, so I again messaged the MM to the above elset value.
Eccentricity is a guess only.
I'd appreciate anyone doing a better elset fit to the positions above.
