July 25th 2012 at Portballintrae on the Co. Antrim coast. This was facing towards the anti-solar point, by that I mean the sun was behind me and I was observing the sky directly opposite towards the N where the parhelic circle can be seen as a white ring crossing the frame where it continued around the E sky and returned once again to the sun, in effect I could rotate 360 degrees and follow this huge ghostly ring in the sky, this is what's called a 360 degree or complete parhelic circle. I had only seen a partial specimen in the past during the night from the moon but never before had I observed a complete parhelia in the daytime sky, also of interest is a colourless enhancement on the ring to the R of centre called a 120 degree parhelia, both of these are rare specimens for optics hunters, at least rare from our latitude. Optics are a thrilling and complex field of observational sky watching to get involved in, read the report for more information. * All images are available for sale in the form of photo prints, canvas or digital files for licensing, if you are interested in a purchase simply drop me an email. |
