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...

Re: Optical phenomena on ice (Taivaanvahti, 21.2.2018)

The same effect is visible, approx 5...8 sec from start of a video. https://drive.google.com/file/d/1QzJn8CENCtJ-gxX0oTvXF-_OhVNucpKV/view Comments...
