Old Sol is acting mean

2013-04-11 14:51 UTC Sun Erupts, CME En Route

NOAA Region 1719, located near center of the solar disk today, produced an R2 (Moderate) Radio Blackout, quickly followed by an S1 (Minor) Solar Radiation Storm, at 1716 UTC (3:16 a.m. EDT) today, April 11. A Coronal Mass Ejection also occurred, and given its trajectory, model runs suggest it will pass Earth, causing what forecasters now expect to be G2 (Moderate) Geomagnetic Storm activity. The Geomagnetic Storm is expected to start in the mid to latter part (UTC) of April 13. The source region is still potent and well-positioned for more geoeffective activity in the next few days. Updates will be here as conditions unfold.

Oh!

So does this mean our “spring” weather will finally warm up? (global warming)

Early this morning the sun erupted, sending billions of solar particles into space at over 600 miles per second, raising the prospect of solar radiation storms above the Earth, according to NASA. A spokesman said the resulting emissions sparked a short-lived radio communications blackout on Earth

Basic arithmetic: 93,000,000 miles at 600 miles per second means gives 155,000 seconds of travel time. That's 2583 minutes, or 43 hours. Either the eruption was two days ago, or it has a while to go before they can run this report about a communications blackout on earth.

Wonder if the aurora is going to put on a show up north?

Interesting. Here's a visible light image I took yesterday. The offending region is in the northern hemisphere just to the left of the center.

STRONG SOLAR FLARE: The magnetic field of sunspot AR1719 erupted on April 11th at 0716 UT, producing an M6-class solar flare. NASA's Solar Dynamics Observatory recorded the explosion's extreme ultraviolet flash:

Coronagraph images from the Solar and Heliospheric Observatory (SOHO) show a CME emerging from the blast site. The expanding cloud should hit Earth's magnetic field during the early hours of April 13th, possibly sparking geomagnetic storms and auroras.
