ANOTHER FARSIDE EXPLOSION: The Earthside of the sun is quiet. All the action is on the farside. For the third time this week, SOHO has detected a significant farside CME.

The storm cloud was hurled into space by an unseen solar flare on April 13th. If Earth were in the line of fire, a strong geomagnetic storm would be in the offing. Instead, Mercury will take the direct hit. CMEs hitting Mercury can scour material from the rocky planet's surface, adding material to its comet-like tail.

GEOMAGNETIC STORM WATCH (G2-CLASS): A CME is heading for Earth, propelled by the unexpected eruption of dead sunspot AR2987. NOAA forecasters say that G2-class geomagnetic storms are possible when the CME arrives midday (UTC) on April 14th. During such storms, auroras can seen as far south as, e.g., New York and Idaho (geomagnetic latitude 55 degrees). https://spaceweatherarchive.files.wordpress.com/2022/04/s_explosion_crop2.gif?w=507&zoom=2

SUBSIDING GEOMAGNETIC STORM: A geomagnetic storm that began on April 14th when a CME hit Earth's magnetic field is subsiding. At its apex, around 1800 UTC, the storm reached category G2--a moderately strong event. The only thing that prevented widespread aurora sightings was daylight. In Europe and North America the sun was out.
"The storm had begun during daytime, so I was unsure how much action I would get hours later when the sun finally set," says Robbin Gälliner of Frösön, Sweden, who photographed the subsiding storm after local nightfall.

SOMETHING FLARE-Y THIS WAY COMES: A potentially large and very active sunspot group is about to emerge over the sun's northeastern limb. For the past week it has been hurling CMEs and plumes of plasma into space from its location on the farside of the sun. Now, it is turning toward Earth. The leading edge of the sunspot group can already be seen right here.
