Guest GDMorgan Posted November 19, 2015 Share Posted November 19, 2015 I'm just curious, with how close these two sunspots are together, why are they considered two different sunspots and not one? Is it due to the where the polarities are in relation to each other? Link to comment Share on other sites More sharing options...
Marcel de Bont Posted November 20, 2015 Share Posted November 20, 2015 Good question. You can see this by looking at the SDO HMI magnetogram. You see that the polarities are separated of each group. 2454 in the north and 2456 in the south. Each group has a negative (west) and positive (east) area which are clearly separated from the other sunspot group. My amazing photoshop skills should help you out: Link to comment Share on other sites More sharing options...
Guest GDMorgan Posted November 20, 2015 Share Posted November 20, 2015 I had thought that might be the case, thank you for the clarification, if either of them intensifies and gain magnetic complexity that spills into the other, would they merge? or would it still be known as 2 different sunspots?

Marcel de Bont Posted November 20, 2015 Share Posted November 20, 2015 Not sure, depends how it would look on the magnetogram I guess but as long as it can be separated it would be classified as 2 groups I think. Link to comment Share on other sites More sharing options...
