The sky looked promissing at dusk but soon a lot of small clouds
came in with only a few clearings in between.
Could nevertheless image several satellites.
Inspired by Bram Dorreman the camera was pointed at the objects
from the 2018 099 launch. Several objects were imaged.
Nice to see how the orbital plane, with satellites spread all along, slowly
moved to the west (or rather the earth turned to the east).
18 099F is rather bright, the others were faint.
18 099W is also brighter, this is the PSLV r/b.
Will try again one of the next night as weather predictions are good.

Just after 22 UT the clouds became thicker ending the session.
