The latest mini-solar storm impact has been mild thus far, but the larger solar storm has yet to arrive. The new #SpaceWeatherWoman forecast goes into detail about what is happening now, including the big radiation storm hitting Earth. Find out how long radio communications & GPS reception will be impacted, see when aurora & meteors might be visible this week: youtu.be/uXmqB-s9p0c

Here is the full 3D interactive animation showing the first of the coming solar storms. Launched during the X1.1-flare on June 30, this storm uses the NASA/M2M fit, coronagraph imagery from GOES, SOHO, & STEREO-A (shown below). This takes about a minute to load: shorturl.at/NC2Qa

Absolutely stunning footage of last night’s geomagnetic storm as seen from the ISS.
Russian cosmonaut Sergey Kud-Sverchkov said it was like flying straight through them.

The expected geomagnetic storm has arrived at G4/Severe conditions. The geomagnetic storm is expected to continue throughout tomorrow (Tuesday, 20 January) with G1 to G3 conditions and a possibility of further G4/Severe storm levels.

The South African National Space Agency (SANSA) has put out a warning for elevated geomagnetic storm activity to affect the Earth on Tuesday. tinyurl.com/598u3k9s

A strong geomagnetic storm has been interfering with Global Navigation Satellite Systems (GNSS) and other technological systems since last night and storm conditions are likely to continue into the rest of the week.

A whole train of big #solarstorms are on their way, along with some smaller storms hitting now, and some fast solar wind! It is an #aurora photographers dream starting now and lasting at least through the weekend. Right now, the biggest of the storms should hit late Thursday or early Friday morning and is well-represented in NOAA's prediction model. You can also get a 3D view of the coming solar storm in my earlier post. G3 to G4 storm levels are possible by Friday.

A G3 (Strong) geomagnetic storm warning has expired as of 13/0600 UTC. A G2 (Moderate) geomagnetic storm warning remains in effect until 13/1200 UTC primarily due to proximity CME influences.

G3 Storm Reached on New Year's Day - 2025! The 2nd anticipated CME roared over Earth late on New Year's Eve night and passage continues as of this post. Will the CME passage continue into tonight? Too much info to put here, so for the full story, visit swpc.noaa.gov/news/g3-storm-…

The G4 (Severe) Geomagnetic Storm Alert threshold was reached on January 1st, 2025 at 1241 ET due to continued effects from the CME's that left the Sun on December 29th.
Stay tuned to swpc.noaa.gov/ for updates!

See those yellow highlights? That's tomorrow night, North America. There are big error bars to these projected times. Projected magnitudes are major. Remember May 10-11?
#SpaceWeather #CME @AuroraBorealis
Stay tuned.

A geomagnetic storm is about to impact the Earth over the weekend, following the biggest solar flare observed for the current solar cycle.

This is incredible; we received reports of visible aurora in Gansbaai last night.

Although low confidence modeling of the CME related to yesterday's X5 flare event determined the possibility of shock influences near Earth early as 2 Jan. A minor geomagnetic storm watch valid 2 Jan is in place. swpc.noaa.gov/products/auror… for the Aurora-30 Minute Forecast model.
