Autumn halo display

Here's a random shot during the event, not very impressive though, rest of the shots were more or less the same but sufficient enough to stack.
Forgot to mention that the image above consists of 113 frames stacked together with help of a Registax software.

Bright 22 halo

07.6.2010 (17:18 - 17:38 GMT +2, 42 frames)
 
For this simulation the main contributor are randomly oriented short-shaped column crystals. Minimum amount of plates were used for parhelias and for weak CZA. Long-shaped columns were used for weak tangent arc and for upper suncave Parry arc, the latter shows up faintly on the stacked photograph.
It's worth to mention that in case when randomly oriented long-shaped columns were used the 22 halo bocame very diffuse so shorter columns were needed. The software used for simulating this display is Halopoint 2.0 by Jukka Ruoskanen.

This was one amazing summer display, the sun was low but halo is still full.

Can you spot the infralatereal arc ?

On imag above the separation between the CZA and 46° halo is visible particularly well. The sun elevation is 28.9-27.6°.
After enhanceing the image in Photoshop the supralatereal arc becomes visible as well. Note: there is also an infralatereal arc on the right side.
 
Here the sun elevation is 21.5-19.6°. 22° halo still remains strong and tangent arcs are clearly fainer than 22° halo. My vote goes to 46° halo.

CZA

A single CZA across the sky. The image really do not justice the actual brightness and size of that arc...still I have seen better ones, like this back in 2006 October.

A day in nature

03.5.2009

The 22° halo was visible most of the day. Later circumzenithal arc, tangent arcs and sundogs.

22° halo oli nähtaval terve päeva. Hiljem tekkisid seniidikaar, puutujakaared ja päikesekoerad.

Päeva jooksul sai tehtud
33km pikkune jalgratta-jalgsi matk. Suurema osa päevast võttis enda alla Suure-Arusoo alasid läbiva Vasalemma jõe kaldaalad, millest läbimurdmine ei ole kerge asi. Tasuks on maalilised jõevaated, mille kohal kaarduvad puud ja päikesevalgus, mis asetab jõepinnale läbi puuokste valguse- ja varjudemängu.
Huvitaval kombel elab Vasalemma kärjääri ümbruses ning Suure-Arusoo ja Ohtu kandis palju põtru ja muid elukaid, hoolimata tihedatest lõhkamistöödest.

A hot spring day

27.4.2009

A short lived display. When I finally got out and set up the gear it was too late. Contrails and other low clouds started ruin the show. Not to mention extremely bright and broad sunlight. It was difficult to measure the light so I snap multiple exposures at time to be safe.

Kiiresti mööduv vaatemäng. Kui ma lõpuks voodist välja ja õue sain oli juba liiga hilja - kondensatsioonipilved ja muud madalad pilved hakkasid peale trügima. Ka valgus pildistamiseks polnud parimate killast, päike ja pilved selle ümber olid pimestavad, seepärast tegin korraga mitu erineva säriga kaadrit, et kindel olla.
