The Lapinjärvi halo display of 10th of April got a sequel in 11th of April! Also today a full parhelic circle was visible with both 120° parhelia!

When this display was at it’s best, the parhelic circle was rather bright and so was also the 120° parhelia, and during the best part of the display, both 120° parhelia were visible at the same time! It was really a magnificent halo display!

Here’s some photos from the display of 11.4.2012

On 10th of April 2012, in Lapinjärvi, Finland, I observed one of the best halo displays in my life so far! In the morning, the display started with 22° halo, circumzenithal arc and 46° halo. Later around noon, the best part of the display started! Then 22° halo, infra- and supralateral arcs, parhelia, parhelic circle and 120° parhelion were visible!

All halo forms that I observed during the day, were very well developed, which means, that the crystals that caused the halos were perfect in shape and they were floating in very stabile positions! The halos were clearly visible visually, but I used unsharp mask to enhance the halos in the photos.

During the Holy Saturday, the sky was clear and the weather was absolutely beatuful! But that also meant, that there weren’t any halo visible in the sky. But that changed during the First Easter day, when 22° halo appeared in the sky! Later in the evening, also upper 22° tangent arc, sun pillar and sun dogs joined in the sky with the 22° halo, that actually had already got a little bit fainter.

I went to see my family in my home place in Ulvila, Finland for easter time. During the Maundy Thorsday I travelled with a bus from Turku to Ulvila. In Turku I spotted a 22° halo in the sky. While sitting in the bus, I noticed that also sun dogs and 22° upper tangent arc had appeared in the sky with the 22° halo. I did this observation when the bus was driving somewhere in municipality of Pöytyä, SW Finland. The 22° halo was still in the sky also when I arrived in Ulvila.

Halo spring 2012 has started!

Halo spring 2012 has started, and there has been halos visible in the sky in many days!  The halos that I have observed, have mostly been common halos. Here’s a small photo gallery of the halos that I’ve seen during the early halo spring this year:
