Another noctilucent clouds display, this time observed from public observatory Bussloo.
A brief display of noctilucent clouds as seen through my bedroom window. It only lasted for 10 minutes.
Despite poor weather forecasts, the sky cleared for a couple of hours right on time for the grazing occultation of star HD69809 (Cancer, m=7.9). The occultation was visible from Public Observatory Bussloo (Netherlands). Six observers in total gathered at the observatory in preparation of the occultation. Hendrik Beijeman and Tom Borger found a place 500m to the south of the predicted limit line and observed two occulations. Jan Maarten WInkel was observing from a site 1400m south of the line and observed a short occultation followed by the complete disappearance of the star. Alex Scholten was the most southern placed observer 1700m south of the line and he saw a complete disappearance. Mark-Jaap and myself observed from the observatory, 250m south of the limit line. Mark-Jaap shot the occultation with a Celestron C8 and Canon EOS 70D in video mode. I used the observatories’ Celestron EdgeHD1400 with a Watec902 camera, a EZCap frame grabber, AME Video Time-Inserter TIM-10 and VirtualDub.
At the observatory two occultations occurred:
21.36.47-21.36.57 and 21.37.44-21.37.45 (timings in UT).
See below movie clip covering the period 21.36.30 – 21.38.00 UT.
Very poor conditions; high clouds, humid and a very light sky background. Couldn’t get rid of a strong gradient caused by light pollution.
Caught a glimpse of the Northern lights, hours after a Kp=8 storm hit the atmosphere.
