#PSA: the solar weather is demanding equal billing with #Milton2024.

@DoomsdaysCW reports solar storm warnings - and another flar today.

Another #XFlare / Severe #GeomagneticStorm Watch via #SolarHam October 9, 2024 @ 15:50 UTC (UPDATED) "A moderate (S2) to Strong (S3) radiation storm remains in progress following the energetic X-Flare produced by #AR3848. "A severe (G4) geomagnetic storm watch was officially added beginning tomorrow when the fast moving CME associated with the flare event is expected to sweep past Earth. While there are no guarantees, a repeat of the geomagnetic storm and aurora event back in May could be on the horizon. "Oh... and an impulsive X1.4 solar flare was observed around departing AR 3842 at 15:47 UTC (Oct 9)."

H/T @DoomsdaysCW for the link!

@g7izu has an excellent report, with implications for radio interference.

Be aware that radio - including wifi, bluetooth, cellular - will be impacted, particularly starting evening of the 10th.

Attached: 4 images Space Weather Bad news for hurricane emergency networks: An X1.8 flare peaked at 01h50 UT. An X1.4 flare peaked at 15h47 UT. These will cause periods of degraded HF communications. A 10cm radio burst was observed at 15h45 UT. Type II and type IV radio emissions have been observed. These will cause short bursts of noise on higher frequecies, potentially disrupting GPS, mobile and satellite communications. A strong S3 solar radiation storm started at 12h30 UT, causing degraded HF communications across polar regions. Geomagnetic Storm Warning: A significant increase in geomagnetic activity on the 10th and 11th of Oct due to three Earth-directed coronal mass ejections arriving in short succession late on the 10th and the early hours of the 11th. #spaceweather #amateurradio #aurora #hurricanemilton #milton
