Moon and Mercury

Veikko Mäkelä, Ursa (Helsinki)

I had to try that encounter after a bit of talk about it on the channels and also wondered how well the observational image I drew in the Stars 2022 yearbook would be true. It looked a bit unhappy with the clouds, as there were clouds on the horizon just west-northwest. I have to say that there was quite a bit of luck that the Moon happened to be found almost immediately in the clouds, even with the naked eye. It's easy and clear. The country house was also visible with binoculars. Mercury bongas with binoculars and had time to show for maybe a minute, but it was still verifiable. After th...

One halo form

Veikko Mäkelä, Ursa (Helsinki)

I was going to visit a pharmacy and shop. Already on the corners of the front door I bongas the pillar-like style above the Sun. It just didn’t really get pictures on my cell phone. Along the way, I tried to make a hole in the loons from which the halo could have been better described. It was not until the corners of Viikki Prisma that the Sun got behind the distant house and the pillar became clearer. The cause of the halo was not quite clear. There weren't even any high clouds on the horizon, so I interpreted the halo as somehow related to low / middle clouds. This was my last sighting i...
