A section of parhelic circle with a 120 degree parhelion over Noordwijk, the Netherlands.

    Nice capture. The 120 parhelion is not often seen.

    Thanks, Frank. Despite being a professional sky watcher (astronomer) and having seen many, many interesting phenomena over the years, I’d never seen the parhelic circle before. Luckily, I had my camera phone to hand and was able to capture it that day. Unluckily, I didn’t have it with me when almost one year later to the day and at the same location (my work), I saw it again … :-(

    Anyway, this is my first post here, having discovered this lovely site very recently. I’ve since been trawling through my photo collection to find other things to post (I’m forever taking pictures of clouds) and one thing I found last night was a lovely picture of a 22 degree halo, upper tangent arc, and regular parhelion … all accompanied by the smoke trails of the Red Arrows. I’d completely forgotten about it: will send it in soon.

    Thanks for the comments, everyone: much appreciated. I have submitted some additional pictures to CAS and hopefully those will appear over the coming weeks. In the meantime, it seems as though I’ve seen some spectacular halo displays every few days recently, and have even managed to photograph some of them. Will send those in too at some point. So many pictures, so little time ;-)
