It took me quite a while to find active area 900 today — at first I thought it had totally disappeared. However, after a short while I managed to find it but all of the spots appeared to have faded a lot. I could just about count 5 spots in the area.

At around 09:00 UT I initially noticed a bright and colourful partial halo around the Sun. I grabbed my mobile phone and, with the camera in it, took this image:

Over the course of the next 90 minutes or so the cirrus cloud seemed to get thicker and spread out more. During this time the halo appeared to lose colour but also to grow in size:
