CMX Posted Saturday at 06:44 AM Share Posted Saturday at 06:44 AM Why do sunspots start on the leftmost surface of the sun facing the earth and decrease or disappear as they move to the far right, that is, when they leave the earth's frame?

Sam Warfel Posted Saturday at 01:22 PM Share Posted Saturday at 01:22 PM The sun rotates in that direction, so every 11 days the surface moves past us, and so sunspots appear to move by with it. Link to comment Share on other sites More sharing options...
CMX Posted Saturday at 02:15 PM Author Share Posted Saturday at 02:15 PM I've been watching sunspots for months, and I haven't seen a new area forming to the right of the sun. Link to comment Share on other sites More sharing options...

Either yesterday or the day before AR3717 formed in the western hemispher, or the right side of the sun. 1 Link to comment Share on other sites More sharing options...
