Looking good already grafana.gafner.net/goto/mOPvzzi...

The G4 did not occur as predicted by the SWPC. Let's hope that the ionosphere recovers quickly and that we can continue to benefit from the relatively good ionization for some great DX. Happy hunting! #hamradio #spacewx

Thanks for your reports that SSTV seems to be off during multiple recent passes. We did receive some early decodes into the gallery followed by these notes on social media. The ops team is investigating and we'll share updates when available.

The Kp has reached a maximum value of 9- so far during this event. This is the same as the October 2024 storm in terms of Kp, but still shy of a G5 classification which needs a full Kp 9. Still very impressive, though!

⚠️ G3- Strong K-Index 7

RIP, Canada.

Severe (G4) geomagnetic storm watch is officially in effect beginning tomorrow November 12th. Fast moving CME from X5.1 flare predicted to pass Earth.

Correction - the outage is scheduled for 13-November, but that is Thursday. We regret the error.

S59P Antenna

Here are the effects of the X5.1 flare on our ionosphere. This plot shows which areas may have radio signal disruptions. The sunlit side of Earth saw a radio blackout during the flare, and the polar regions are now experiencing some disruptions due to the radiation storm.

Bright halo CME heading directly for Earth. Impact will be likely early on November 13th (UTC). Strong (G3) to Severe (G4) geomagnetic storm watch will likely be added. SolarHam.com

Tsunami threat passes following magnitude M6.9 quake off coast of Iwate, then aftershocks of between magnitudes 5.3 and 6.3—no abnormalities at Onagawa nuclear power plant. More than +50 EQs past 7-days, largest was M6.8 Ocean Earthquake near Yamada, Iwate, Japan. Map & data

I am sure right now NOAA and NASA are busy modeling this eruption, and that will help us determine an arrival time at Earth with potential geomagnetic storm levels. I don't want to speculate too much, but I do think NOAA SWPC will upgrade to a G4 watch, now for Nov 12.

Here is the X5.1 flare in straight EUV light. We are looking at the 193 Å "gold" filter here. The flare is the bright flash, and immediately, you can see a giant blast wave racing through the Sun's corona, lifting tons of plasma into space as an Earth-directed CME.

Major solar flare in progress. The latest event is now peaking around the X5 level and the source is AR 4274. More to follow.

X5.1 solar flare around AR 4274. Proton levels are already on the rise. Wide area of coronal dimming evident meaning a large Earth directed CME is likely. SolarHam.com

CMEs will severely disrupt High Frequency (HF) radio propagation. G1, G2, G3, & R3 w/ X1.8-class solar flare & Big sunspot 4274 erupted. Multiple CMEs arrive per NOAA w/ x3 CMEs hitting Earth—Nov. 10th thu 11th, Geomagnetic Storm Watches for 11-13 Nov. www.swpc.noaa.gov/products/wsa...

HamTV outage upcoming Wednesday. HamTV transmissions will take a pause on Wednesday to enable other human research payload operations. When operating, HamTV is transmitting a signal but no media is being sent. We'll share when future uses are planned.

We are seeing a surge in sunspots and major flare probability on the Sun! Look at how peppered the Earth-facing disk is right now, dominated by AR 4274 which is transiting the Earth-strike zine. It is in a perfect spot to launch CMEs directed towards us, but will it? Let's find out!

We are currently experiencing a G3/STRONG geomagnetic storm. The current estimated planetary K-index is 6.67. The Bz does look to be rotating northward within the next hour, but northern lights displays will persist a bit longer. The system will take time to cool down.

Woah… if the current Dst value of -136 nT holds, this will be the third strongest geomagnetic storm of 2025. Pretty crazy! April 16 (-138 nT) and January 1 (-212 nT) are the only stronger storms this year.
