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.

Minor G1-class geomagnetic storms are underway on Nov. 24th in response to a high-speed stream of solar wind. 
The stream arrived today, and it contains gaseous material moving faster than 700 km/s (1.6 million mph).

The British Geological Survey (BGS) has upgraded its geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm, which prompted the aurora displays that entertained stargazers across the UK overnight.
Current predictions suggest that a second storm, feeding off the first, will result in potentially the largest solar storm to hit our planet in over two decades. Scientists believe that it has the potential to achieve the maximum level of G5 on the NOAA storm scale. Dubbed a ‘cannibal storm’, the first event has already disrupted communications and global positioning system (GPS) satellite accuracy. At ground level, it created the biggest measured geoelectric field since BGS records began in 2012.
The increase in activity from the coming storm could have further, significant impacts on space and ground-based technologies, including communication systems, global positioning systems (GPS) and satellite orbits.
Geomagnetic storms are caused by solar activity interacting with the Earth’s magnetic field, which has implications for national energy infrastructure and navigation. For this reason, it is listed as one of the primary hazards on the UK’s National Risk Register.
Space weather can have a real impact on the lives of people across the planet. BGS records real-time data of geomagnetic conditions, underpinning the national forecast service. Our data suggests that this event could be one of the biggest storms we’ve seen in 20 years.
Like any forecast, it is not possible to say with certainty exactly how big the storm will be. Solar storms travel from the Sun and can reach Earth in as little as 17 hours, although they can also take significantly longer. Based on satellite observations, we anticipate this event will be significant; early indications such as ground measurements of solar energetic particles are some of the largest recorded since 2005.
Assuming clear, dark skies, there is an increased chance of seeing the aurora borealis from the UK tonight. Observers in Scotland, northern England and Northern Ireland have the best chance if the weather is
favourable.

THE STORM IS NOT OVER: Last night, auroras spread across the Americas as far south as El Salvador during a severe geomagnetic storm. The lights were seen in at least 45 US states. It could happen again tonight if another CME arrives, as expected. NOAA predicts more severe storming on Nov. 12th.  Full story @ Spaceweather.com.

Two CMEs are coming…
South  Africa audible now on 1548.  The Greek pirate has been off air for some time now (or running low power).
At peaks Radio Islam from RSA is almost readable here.  First good peak was at 2011 UTC.

MAJOR SOLAR FLARE AND EARTH-DIRECTED CME: Today, the sun produced one of the strongest solar flares of the current solar cycle: An X5-class powerhouse. The explosion hurled a very fast CME toward Earth. This CME could scoop up one or two CMEs already in route, forming a potent “Cannibal CME.” Its arrival on Nov. 12th could cause severe geomagnetic storms. Full story @ Spaceweather.com.
