Halo display in Himos on the night of 2/3 February


On the evening and night of 2-3 February 2009, I was testing my new HID-spotlight that I finally got earlier on that same day. What would be better place for testing than nearby Himos ski resort in Jämsä, Finland. After being there for a few hours and seeing nothing but 22° halo with my lamp, I decided to go home. Luckily, at the same time, the sky started to clear and I first saw a half moon and Parry arc on that. Then I noticed also 46° halo and quickly took a few pictures and started heading back closer to Himos where I found a place to set up my camera and lamp. I stayed on that same location all the time, because there was some wind and things may change quickly.

Lamp elevation was about 2 or 3 degrees. Haloes were supralateral arc, parhelic circle, Wegener, subhelic, suncave Parry, Parry supralateral, 46°halo, Tricker, Greenler, "Ounasvaara arc" ( 1 ) (first observed by Marko Riikonen -07) and more. Temperature was between -7 to -10 C. See a few pictures and videos ( 2 ).

  1. That's a good start with the new lamp, Mika. Very sharp column stuff.

  2. Yes very sharp indeed. I was outside tonight doing some snow gun halos and for parhelia and nice pillars. My first homemade halos. Something everyone has been wondering when I was going to get done which I was able to GIT R DONE.

  3. Good catch! The Moon display is also fine (for a 50% illuminated Moon), but yeah, lamp display is again something else. Very nice display. Maybe one of the last ones of the season.

  5. Congratulations, Mika! Really nice catch. And Michael, I'm really glad you could start experimenting with halo making. I'm sure you'll get some pretty good displays in the future.

  6. Yeah I Agnes I hope to but so far I got pillars parhelia and when light was below horizon I got subparhelia with possible reflected lowitz hard to tell but When air compressor is moved outside I will have the paint gun autofed from a 5 gal pail.
