Comments: School's out for summer - and I have time for
observations again. It's been way to much this year with
all the preparation for school exams etc., so I'm very
happy not to simply fall asleep early on weekends but
rather see the night sky again. Stress is way worse than
light pollution, I can tell you!
Perseids are waking up. There were two real nice ones
with trains. On 29/07 we had a bad thunderstorm, so I'm
still waiting for the skies to recover.
Please note: d = degrees, all times in UT
