Mostly cloudy day with a fair bit of wind. During a reasonable break in the clouds I took the Solarscope out to do a quick sunspot count.

The count was quite tricky today due to the wind blowing the Solarscope about. However, despite this, I could see a single large spot in active area 904. No detail could be seen, possibly due to the conditions but mostly down to it being very close to the limb (I expect that it won't be visible tomorrow).

A short while later I noticed what appeared to be another spot on the opposite limb. Because it looked like there was a small, shallow "bite" out of the limb I first took it to be an obstruction in the Solarscope somewhere. I rotated the tube and moved things about a little but it stayed in the same place suggesting that it really was a new spot, right on the limb.

I then checked online and a couple of space weather sites had evidence of it but no ID was noted (in fact, SpaceWeather.com were showing it with a question mark against it).

Some time later I found out that it had been given the ID 905.
