Observing in Christmas night

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!

Unvisibility report of the December total lunar eclipse

Observed phenomena: Lunar eclipse
Type of eclipse: Total
Type of observation: Negative
Date and time: 10.12.2011, 16:00
Observing place: Sodankylä, Finland
Observing conditions: Cloudy sky, snowing

Weather conditions were poor during last night’s lunar eclipse. The sky was cloudy and it was snowing at least at the time of maximum of the eclipse (around 4 pm). Later in the evening, around 10pm, the cloud cover had became slightly transparent, so that the Moon was visible, but the eclipse was already over then. But it was still snowing!


So this means, that I wasn’t able to see any total lunar eclipses this year. Next one will be in 2015, hopefully conditions are more favourable then!

And I realized that it has also been one year anniversary for Celestial Sphere -blog! The exact date was actually 6th of December.
