Solar Activity & SR

Posting some graphs to document the busy phase in the past day or two.

One X-1.5 flare just hours ago, with 3 almost-X flares in past 48 hours (image above).

Radio blackout in this region:

Look at the CMEs that our Sun spewed out:

Here's what SpaceWeather.com has to say about these "wagon-train" CMEs:

CANNIBAL CME ALERT: A series of M-class flares over the weekend hurled multiple CMEs toward Earth. According to a NOAA model, the first two CMEs merged to form a potent Cannibal CME. Strong G3-class geomagnetic storms are possible when it reaches Earth on July 30th. Subscribers to our Space Weather Alert Service will receive an instant text message when the CME arrives.

The Cannibal CME is clearing the way for 2 or more CMEs following behind it. SOHO coronagraphs show a wagon-train of clouds leaving the sun on July 28th (image above).

These CMEs are flying into a void created by the earlier Cannibal CME. With little interplanetary material to slow them down, the storm clouds should reach Earth no later than July 31st, potentially intensifying any geomagnetic storm already underway. If the G3 forecast is correct, auroras will be visible at mid-latitudes across Europe and the USA on July 30-31. Stay tuned for updates.

I'm still able to access SR readings so here's the last chart for this post:

It took me a very long while before I could finally fall asleep last night (28th) ~ now I know why. And the high-pitched tones! I've mentioned before that I'm rather pleased with myself for being able to tune out these sounds for years now, but last night was exceptionally loud. No discomfort or irritation at all, just very loud. Of course wearing ear-plugs (which I dislike anyway) would be futile because the noise isn't from outside, it's internal. Plugging the ears would only serve to provide a loud echo effect.

Geomagnetic storms are expected to come our way soon, fair warning! 😅

Namarie! 💛


It's An X-9.1!

SpaceWeather We had an X-9.1 flare yesterday, the strongest yet of this current Solar Cycle and the biggest flare since 2017! I wanted to po...
