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:

After a little bit of effort I noticed that active area 900 was visible. Within it I managed to count 5 spots. All were very small.
