Sunspot AR2740 and AR2741

Sunspot AR2740 used to be called AR2738 before it rotated to the far side of the sun. The sun rotates once every 27 or so days (the number of days is different for different latitudes). Since AR2738 survived for more than 14 days, the sun's rotation brought it back to our view again. As a result, astronomers gave it a new name, AR2740.

The image below shows the sunspot taken with a cellphone through a safe solar telescope. If you look carefully to the spot's lower left, there's another sunspot very close to the sun's edge. In a another few days, this spot ought to be easily visible. The spot's name is AR2741.

   
The sun is in a quiet phase, so it's a pleasant surprise to see sunspots at this time.
