Sundogs

 

Sundogs photographed with a smartphone by, friend of the Observatory Lulu,  from water meadows south of Abingdon in Oxfordshire. 

"A sundog is a concentrated patch of sunlight, which may be seen to the left or right and sometimes both sides of the Sun. They, like sun haloes, are caused by sunlight being refracted by ice crystals in the upper atmosphere". - Kurt Thrust current Director of the Jodrell Plank Observatory.

All the above images were captured using an objective lens mounted Baader solar safety white light filter film. IN NO CIRCUMSTANCES POINT ANY CAMERA OR OPTICAL DEVICE AT THE SUN. SUCH WILL SEVERELY DAMAGE YOUR EQUIPMENT AND OR EYESIGHT.

" The weather in Lowestoft has been very mixed of late. The 19th of April began with the sky full of high level hazy cloud. A blustery wind  started at about 12:00 noon and the cloud disappeared. The wind was a problem, vibrating the Observatory's big refractor on its concrete pillar mount, and ruined many of the video frames. It was nice for the team to be out in daylight and sunshine. After a couple of hours in the sun my bald head was quite pink" Kurt Thrust current Director of the Jodrell Plank Observatory.

Circular Sun Halo

 


"Many thanks to our sponsor Anita Roberts for taking this excellent photograph of a circular Sun Halo displaying sunlight being reflected and refracted by high altitude atmospheric ice crystals. Anita spotted this unusual occurrence and photographed it with her iPhone from the Jodrell Plank Visitor Centre.. The sun halo was easily detected with the naked eye but the colours due to refraction were better seen on the image. In all the halo lasted for over 20 minutes". Kurt Thrust current Director of the Jodrell Plank Observatory.

Venus, Mercury, the Hyades and the Pleiades over fields in Cambridgeshire

 


"Many thanks to, good friend of the Observatory,  Chrissy Roberts for sending us this image of the inferior planets Venus and Mercury seen shining brightly over Cambridgeshire. An excellent image taken with Chrissy's Smartphone and cropped and denoised by our own Pip Stakkert." Joel Cairo CEO of the Jodrell Plank Observatory.
