  Another interesting thing about this ss. group is that it has a 'double' polarity separation line. This often seems to lead to big flares!

  Just as a note, it is not really possible to classify a sunspot group using Hale without comparing both vis. light images and mag. images.

  @pahiggins thank you for taking the time to comment. Looks like I will need to do some homework on terminology... 😃

  BTW here is an example of a visible light/magnetogram overlay that can be used to determine if a spot is a delta: http://tinyurl.com/meqwxa4

  @pahiggins, thanks again. 😃 sadly I couldn't get the magnetogram link to work 😦 The blog link worked fine though so thank you.
