"X1.4-class solar flare from sunspot AR1520: Geoeffective Blast !!"


 
 
Dear Doves, I notice recently from SpaceWeather website that there seem to be X-flares coming up. The sun is very much active! Here is a recent one:
 
 
 
X-FLARE! Big sunspot AR1520 unleashed an X1.4-class solar flare on July 12th at 1653 UT. Because this sunspot is directly facing Earth, everything about the blast was geoeffective. For one thing, it hurled a coronal mass ejection (CME) directly toward our planet. According to a forecast track prepared by analysts at the Goddard Space Weather Lab, the CME will hit Earth on July 14th around 10:20 UT (+/- 7 hours) and could spark strong geomagnetic storms. Sky watchers should be alert for auroras this weekend.
