  • May produce a dangerous X-class flare that could directly impact Earth Steve Davidson writes: Right now, today, one of the largest sunspot groups of Cycle 24 – AR1890 – is pointing nearly strait at Earth...
  • Looks like a double peak for cycle 24 is forming As many WUWT readers have noted in comments, October 2013 has been significantly more active than the previous several months, and we have not seen this level of activity since...

  • The NOAA Space Weather Prediction Center has updated their monthly graph set and it is becoming even more clear that we are past solar max, and that solar max has been a dud...
  • Solar cycle 24 continues the slump Tue, 13 Aug 13, 5:01pm
    Sunspot count is virtually unchanged from last month : It seems possible that we’ve seen the double peak, and it will be downhill after this. A similar status quo in radio flux – little change from last month....
  • The solar cycle is still slumping Thu, 11 Jul 13, 5:01pm
    It is looking more and more like a double sunspot peak for solar cycle 24. Sunspot count is down again:  A similar drop occurred in radio flux. The Ap magnetic index remains low, but is up 3 units from last … Continue...
  • Above: note the four separate events in the last two days – from the WUWT Solar Page (From NASA’s Spaceweather.com) When the week began, the sun hadn’t unleashed an X-flare all year long. In only two days,...
  • Despite some small upticks on sunspot and 10.7cm radio activity, the magentic activity of the sun is still bumping along the bottom. A slight uptick was seen in sunspot count.  A similar slight uptick occurred in radio flux....
  • The December data from NOAA’s Space Weather Prediction Center is in, and it looks more and more like the peak of solar cycle 24 has been reached, and that we are now past it...
  • NOAA SWPC has updated their plot page of solar metrics, and the slump continues. At spaceweather.com Dr. Tony Phillips writes: SO THIS IS SOLAR MAXIMUM? Forecasters have long expected the Solar Max of 2013 to be the weakest...
  • The sun – still slumping Tue, 4 Sep 12, 12:20am
    The latest solar cycle update graphs have been released by the NOAA SWPC today, and the anemic cycle 24 continues: The current count isn’t keeping up with the prediction line in red...
  • A quiet cue ball sun Mon, 25 Jun 12, 6:00am
    Source: http://sdo.gsfc.nasa.gov/assets/img/latest/latest_4096_4500.jpg A couple of people have noticed (as did I) that the sun is essentially blank. There was one small sunspot sunspeck 1511 yesterday, giving a sunspot count...
  • Sunspot AR1476 may have some surprises for us in the coming days, and I hope it isn’t a Carrington type event. It has already launched two CME’s yesterday. From NASA’s Spaceweather.com: A pair of solar...
