Re: PL Sichtbarkeit Region Helsinki

I add here one useful link. It picks up all the observations of auroras in Taivaanvahti database (beginning from 1.7.2017, currently 1216 entries). You can zoom the map to Helsinki (or any other region) to get sample photos. This is better local estimate, used together with light pollution maps... h...

If you are getting cold, there is lot of steps to walk up and down :-) There is also a parking place near the hill, last steps you...

Re: 2018-10-10/11: Polarlichtwarnung

In central Finland, I was outside looking at sky a while ago. In northern parts of sky, some forms of green & red auroras were rising to approx 50...70 degrees of height. Just need to take a hot tea with bread, to get some energy for remaining night (+3C outside now). Also heard some swans (approx 5...

Here is my first attempt to capture... I took these images some time ago, now are finally processed. The lens I used was Tokina 12-24/f4 (Nikon D200), at 12mm focal length. Images are not cropped, sun is behind & in the middle of flagpole at bottom right corner. https://timokuhmonen.smugmug.com/Natu...

Re: Perseiden 2018

difficult to follow visually Perseids activity at central Finland. Sky is cloudy :-(

I have already components for 49.75MHz radio-observation. Just need to set up a small mast for the antenna. Approx 8m at height... (2el yagi). Cannot do that for 2018 Perseids anymore...
