Finally I was lucky with observing a Lunar eclipse! The eclipse of 7th of August 2017 was well visible in Turku, Finland.

Only the last phases of the eclipse were visible. The Moon was below horizon during the early eclipse and during maximum eclipse. Soon after maximum eclipse the Moon rose above horizon also in Turku. The Moon rose as it was partially in the umbra, and it was quite an exotic sight to witness! As the Moon rose higher, it was leaving the umbra. The 4th contact of the eclipse happened around 19.18 UT. The penumbra was still visible until about 19.45 UT.

This was a very enjoyable and memorable event to observe! I’m very glad and thankful that I was able to observe this eclipse!

Here are some photos from the eclipse:

I was observing transit of Mercury in Turku, Finland where I had established a pop-up transit of Mercury observing station! This time weather was favourable and I was able to observe this celestial event from the beginning (almost) to the end, and the sky was totally clear during the whole event! The sky of Turku has let me down many times, but not this time! At least I got some compensation after the unlucky observing attempt of transit of Venus in 2012 when clouds ruined the whole event.

The transit started at 11:12 UT when a small hole appeared in the side of the Sun. Soon whole Mercury drifted to the front of the disk of the Sun. During the transit, Mercury passed a group of sunspots. I observed the whole transit as long as I could. I wasn’t though able to observe the 3rd and 4th contacts because Sun was setting behind the trees and because Mercury has disappeared within the layers of mirage -distorted Sun in the very end.

During the day, many people passed by me, and I showed the transit for all that were interested in taking a look at it. During the day, abour 20 to 30 people were able to see the transit!

This was fantastic experience, and I’m so glad and grateful that I was able to witness this rare celestial event!

Below you can have a look at some of my photos of the transit:
