Three weeks in a lesser solar maximum

image226

While the Sun is thought to be approaching the peak its predicted maximum level of activity, a review of the past three weeks in extreme UV light suggests that this might be a very weak maximum. The video, which covers Sept. 3-23, 2013, shows very few solar storms and not a large number of brighter, active regions for a period when the Sun should be about near its maximum. While the Sun could perk up in the coming year or two as some scientists suggest might happen, so far the output has been underwhelming. Credit: STEREO/NASA.
