The sun is still in a funk: sunspot numbers are dropping when they should be rising

The sunspot number for February from SIDC is down again, to 33.1 Here’s the source of that data: http://sidc.oma.be/DATA/monthssn.dat So far, cycle 24 is significantly lower in SSN number that…

Homeland Security takes on The Carrington Event

While we worry about future threats like global warming, and present threats like Iran’s escalating nuclear program, the sun’s propensity for belching out monstrous solar flares (like the Carrington event…

Biggest solar storm since 2005

It is being called by WaPo “The Biggest solar storm since 2005“. The sun erupted late on January 22nd, 2012 with an M8.7 class flare. The Solar Dynamics Observatory captured…

Solar cycle update: sunspots down, Ap index way down

The NOAA SWPC monthly solar cycle update has been published here, and after a big spike last month, the sunspot count is down again. There’s an even bigger drop though…

Big CME hits earth, low latitude auroras possible

From the Rice University Spaceweather listserv Our space weather alert system is in level yellow, and the CME input of energy to the Earth’s magnetosphere still continues. So, if you…
