Very active sun today - July 24th


No sunspots today but still the sun was very active. In Hα however the activity was quit impressive. Using the PST Coronado at least 5 bright "prominence areas" were visible in the afternoon. I tried to capture those on picture but could only realize this afocal one. The picture was edite using CS4.

Noctilucent Clouds - Use of Radar from Leibniz


Clear sky means also good news for observing noctilucent clouds - without an open sky it's anyway hopeless. The radar of the Leibniz Institute can help to predict your chances, but with last night noctilucent clouds above Averbode the radar did not show much movement.
Find here the link to the Radar and some prints taken the last days.


Sunspots AR 2565 & 2567 B&W


Some more editing of the pictures taken of the sunspots AR 2565 & 2567.  This time pictures are put on black/White and sharpen using unsharp masks. Never thought I would get this great result.
