Lacrosses and ISS

Another clear morning, albeit slightly hazy. Targets were Lacrosse 2 (91-017A, #21147), Lacrosse 3 (97-064A, #25017) and the International Space Station.

The ISS was less bright than last Friday, at about mag. -1.5 shortly after exiting shadow in Canes Venatici. It was "white" this time. The positional residues are nice:

STA___YYday_HH:MM:SS.sss___XTRK____deltaT____Perr
4353__06331_05:04:31.100__-0.00_____0.09_____0.054
4353__06331_05:04:41.800___0.00_____0.01_____0.008


Lacrosse 2 (91-017A) was bright (mag. +2) as it came out of shadow and traversed the tail of Ursa Major. I obtaned 1 picture, 2 points. It was 0.4s late and 0.2 degrees off-track relative to an 8-day old elset.

Lacrosse 3 (97-064A) was fainter (mag. +3.0 to +3.5). I obtained 2 images, hence 4 points. was 1 second late but on-track relative to an 8-day-old elset.
