Observing session #5/11-12
About a month ago, I spent couple of weeks in Turku, where nights were already getting dark. I was also able to make some night sky -observations then. But then I had to go north again back to Sodankylä, which also meant that there would be a considerable break for me in the observing season that had just started while I was in Turku.
Nevertheless, now nights are getting dark enough for night time observations also here up north! And this means, that I’m able to re-start my observing season! I did my re-start in village called Aavasaksa in the western Lapland, very close to Swedish border. In the Aavasaksa village is situated a hill called Aavasaksanvaara, and I was able to re-start my observing season on top of the hill in 24/25.8.2011. The night was very short, and I was able to make observations during deep nautical twilight. Anyway, the night was already dark enough that I was able to see the most brightest parts of the Milky Way!
Because I had to be working in the next morning, I wasn’t able to observe all night till sunrise. During the night I made observation of R Cyg, whose brightness had dropped from 10.1 to 11.0. Besides that, I made also SQM -measurements, and I actually got relatively good readings: SQM (zenith) 19,92 and NELM 5,1.
And now I’m just waiting clear nights…
