ISS bit dimmer than predicted

Hi I saw ISS pass almost overhead on Thursday night, culminating close
to the predicted time of 6/18 21:44:35 local time = 6/19 4:44:35 UTC. A
pass from SW to NE.

A nice pass with fairly constant magnitude (partly because the phase
didn't change dramatically). However it was less bright than SkyMap's
predicted -1.3. It never quite reached as bright as Arcturus. So for
this pass at least, the standard magnitude in use was perhaps too

Best, Mark
