X-CLASS SOLAR FLARE AND CME: NASA’s Artemis rocket might be launching into a geomagnetic storm. This morning, an X-class solar flare hurled a fast and massive CME into space. It is expected to make contact with Earth on March 31st, sparking geomagnetic storms on the night before the Moon rocket’s launch window opens. Full story @ Spaceweather.com.

AN ‘EQUINOX CME’ IS COMING: Earlier today, an Earth-directed solar flare launched a CME almost directly toward our planet. It is due to arrive just hours before the northern vernal equinox, setting the stage for amplification via the Russell-McPherron effect. Mid-latitude auroras are possible on March 19-20.

Suddenly, Sunspots Have Vanished
THE FIRST SPOTLESS DAYS SINCE 2022: After 4 years of non-stop sunspot activity, the face of the sun is suddenly blank–no sunspots. The first spotless days since 2022 herald the distant approach of a new Solar Minimum. Full story @ Spaceweather.com.

There are currently 12 sunspot groups on the solar disk, including sunspot 4341, which produced a powerful X2-class solar flare earlier this week.
More flares are likely this weekend, probably of classification.

SOLAR PROTON STORM IN PROGRESS: Energetic protons from the sun are raining down on Earth. They were accelerated in our direction by yesterday’s powerful X-class solar flare (described below). This is called a “solar proton storm,” and currently it is category S3. Shortwave radios inside the Arctic Circle aren’t working right now due to this storm, which is causing a polar cap absorption event. Currently, there is no danger to air travelers.

A CME is coming, and it is expected to hit Earth during the late hours of Jan. 2nd. According to NOAA forecast models, the impact will spark a G2-class geomagnetic storm on Jan 2-3.

A SOLAR STORM IS HEADING DIRECTLY FOR EARTH:  Strong G3-class geomagnetic storms are possible on Dec. 9th when a full-halo CME is expected to strike our planet. The storm cloud was hurled in our direction on Dec. 6th by an almost-X-class solar flare. Full story @ Spaceweather.com.

THE WRONG SUNSPOT KEEPS ERUPTING: All eyes are on monster sunspot 4294-4296, which seems poised to erupt with an epic Earth-directed flare. Instead, the “monster” is quiet and other sunspots are providing the action. On Dec. 6th, northern sunspot 4299 erupted and hurled a CME directly toward Earth. Read the details below–but don’t stop watching the monster. 

EARTH-DIRECTED SOLAR FLARE AND CME: It was almost an X-flare. On Dec. 6th (20:39 UTC), sunspot 4299 produced an M8-class solar flare pointing directly at Earth:

AAtmospheric ionization caused a shortwave radio blackout over the Pacific Ocean. Mariners and ham radio operators may have noticed loss of signal at all frequencies below 20 MHz for 15 to 20 minutes after the flare.

Of greater interest is the CME. Both NOAA and SOHO coronagraphs have detected a full halo storm cloud heading directly for Earth. NASA simulations of the CME suggest an arrival on Dec. 9th. Earth is the yellow dot in this forecast model:

The impact could spark G2 (Moderate) to G3 (Strong) category geomagnetic storms. Mid-latitude auroras mixed with moonlight are possible if the storm reaches the upper end of this range.

New sunspot 4300 erupted today (Dec.4th @ 0250 UTC), producing a strong M6-class solar flare.
At the same time, the US Air Force detected a Type II solar radio burst, which means a CME is probably emerging from the blast site.
Meanwhile, giant sunspot complex 4294-4296 remains ominously quiet.

GIANT SUNSPOT ALERT: Is this the December surprise? A very large sunspot group is emerging over the sun’s southeastern limb, one of the largest of Solar Cycle 25. NASA’s Mars rover saw it first last week, and now it is turning toward Earth. Full story with observing tips @ Spaceweather.com.
