It had been miserably cloudy in Finland during December (at least in Sodankylä). There just haven’t been any opportunities for observing. But then I travelled to my home in Ulvila to spend Christmas there, and finally I also had a chance to see stars and make some observations. I went to the observatory of Porin Karhunvartijat in Ulvila for observing. The sky had been clear in early evening, but I had a bad luck with the clouds, because they started to interreupt my observing just when I arrived in the observatory. Nevertheless, I could make at least one observation, I observed Z Uma in long time, and it’s brightness was around 8 mag. Then I also looked at Jupiter, but I didn’t make any observation of it, because I was already feeling very tired.
Then I also did the usual observations of observing conditions. Now I was finally able to make SQM -measurements also in Ulvila, I did the observations in the observatory (which is situated in suburban area called Krapisto in the eastern edge of Ulvila town), there I got SQM -measurements of ~20.6. NELM was around 5.7.
Then I repeated the same measurements in rural area of Friitala (about 2 km southwest of Ulvila town), where my home is situated. There I got roughly similar measurements. Anyway, it is still too early to make any in-depth conclusions, but now it seems that there is not any big difference between the conditions in Friitala and Krapisto. Of course I should make more measurements, which I will surely do when I’m able to!
