MINOR GEOMAGNETIC STORM WATCH (UPDATED): NOAA forecasters say that minor G1-class geomagnetic storms are possible on June 3rd when a stream of solar wind is expected to hit Earth’s magnetic field. Originally predicted to arrive on June 2nd, the gaseous material is flowing slower than expected from a pair of holes in the sun’s atmosphere.

SURPRISE GEOMAGNETIC STORM: Surprising forecasters, a crack opened in Earth’s magnetic field last night. The resulting geomagnetic storm sparked naked-eye auroras across many northern-tier US states with photographic auroras descending all the way down to mid-latitudes. The event may have been caused by a near-miss CME. Full story @

PARTIALLY ECLIPSED X-FLARE: A powerful M9.6-class solar flare erupted from behind the sun’s southeastern limb on May 16th, just percentage points weaker than X-class. In fact, it probably was an X-class solar flare partially eclipsed by the edge of the sun. The blast heralds a hidden but active sunspot, which could turn toward Earth later this week. Full story @

The Arctic Circle is in the grip of a radio blackout due to a polar cap absorption event occurring, all thanks to the sun’s activity.

This has led to radio frequencies below 15 MHz being nearly completely blacked out and most frequencies below 35 MHz being at least a little bit degraded, according to NOAA’s Space Weather Prediction Center.

This polar cap absorption (PCA) event is occurring as a result of a coronal mass ejection that occurred on May 7 that is now colliding with our planet.

HERE COMES ANOTHER CME: An approaching CME is peppering Earth’s atmosphere with energetic particles, causing an S1-class solar radiation storm and a polar radio blackout. The CME itself will reach Earth on May 10th, bringing a chance of geomagnetic storms and auroras. Full story

ANOTHER CME IS COMING: NOAA forecasters say that minor G1-class geomagnetic storms are possible on April 27th when a CME is expected to hit Earth’s magnetic field. It was hurled into space on April 24th by an explosion in the sun’s southern hemisphere. Most of the CME will sail south of Earth, but its northern flank will probably touch our planet.

SEVERE GEOMAGNETIC STORM IN PROGRESS: Arriving earlier than expected, a CME hit Earth’s magnetic field today, April 23rd, at 1737 UT. The impact sparked a severe G4-class geomagnetic storm with auroras sighted in Europe sighted as far south as France. The storm is still going on and it is starting to produce visible auroras in the USA as well. Here is a picture from Kentucky! Stay tuned for more auroras as night falls across North America.

AN EARTH-DIRECTED EXPLOSION ON THE SUN: Yesterday (April 21st), a large magnetic filament snaking across the sun’s southern hemisphere exploded, hurling a CME straight toward our planet. Estimated time of arrival: April 24th. Minor to strong geomagnetic storms are possible when the CME strikes.
