Massive solar flare and CME from old Sunspot 1678

   Old region 1678 which is due to return during this coming weekend produced a MASSIVE solar flare and a spectacular full-halo coronal mass ejection.

   Unfortunately, it is not heading our way because this was a farsided event. But its heading for the STEREO Behind spacecraft.

No C class solar flares took place yesterday and no notable B class solar flares.
But this morning  an impulsive M1 class solar flare took place. Peaking at 07:54 UTC around Sunspot 1686 in the southwest quadrant.

Comets Lemmon and PanSTARRS Peaking

Two impressive comets will both reach their peak brightness during the next two weeks. Taking advantage of a rare imaging opportunity, both of these comets were captured in the sky together last week over the Atacama desert in South America. Comet C/2012 F6 (Lemmon), visible on the upper left of the above image, is sporting a long tail dominated by glowing green ions. Comet C/2011 L4 (PanSTARRS), visible near the horizon on the lower right, is showing a bright tail dominated by dust reflecting sunlight. The tails of both comets point approximately toward the recently set Sun. Comet Lemmon will be just barely visible to the unaided eye before sunset in southern skies for the next week, and then best viewed with binoculars as it fades and moves slowly north. Comet PanSTARRS, however, will remain visible in southern skies for only a few more days, after which it will remain bright enough to be locatable with the unaided eye as it moves into northern skies. To find the giant melting snowball PanSTARRS, sky enthusiasts should look toward the western horizon just after sunset. Deep sky observers are also monitoring the brightening of Comet C/2012 S1 (ISON), which may become one of the brightest objects in the entire night sky toward the end of 2013.


  1. Just incredible!

    Extreme power like we haven't seen in a long old while,hope Sol picks himself back off the extreme UV and back into X-Ray land.

    Good stuff as always MSA Crew : )

    <--- Fuzzy Proton Chart by the way Folks.
