Development of Sunspots

[3gMike]

Whilst attempting to understand how individual sunspots might develop, based on knowledge of the magnetic fields, I noticed that Alpha spots (at least those I have observed - in real-time and in the archive) generally develop as the leading spot and therefore will have different polarities in each hemisphere. Wondering why this should be, I searched a few articles and found this from Daystar filters which seems to give some good information http://www.daystarfilters.com/SunspotClass.shtml

I hope others will find it useful.

3gMike: I sent the same link to a friend before you posted this, because I thought it had a great description of sunspots etc, but he ended up buying a daystar filter for his telescope. I don't know if he even looked at the info!
