are 3 that use. I used to use the NOAA page (which is the last one) but occasionally they have a holiday and stop posting, so I had to fine the others.

Search for "Active solar region maps", I'm sure you'll find plenty of others as well. They also help to orient your images:thumbsup:.

Interesting links.

Can anyone describe how the numbering system works?

Perhaps it's a topographical pointer...?

When "they" decide an Active Region/feature warrant's recognition a sequential number is allocated......

Who are 'they'? I have often seen large AR rounding the limb with no allocated number from such sites - Can I name them?

[Merlin66]

Matt,
I'm sure you could ;-)
but the NOAA designation would probably take precedence.

Not well versed in Solar. But maybe this link will help. I enjoy going there.
