@tomdf5jl.bsky.socialThis weekend geomagnetic activity is expected to be mostly quiet to unsettled (Kp 0–3), with occasional active to stormy periods (Kp ≥4), likely late SUN, early MON. Solar activity has continued to increase, the risk of solar flares remains moderate (M55% X10%). #spaceweather #hamradio #hamr
@lumina.observer🔴 Extreme geomagnetic variability
Extreme swings in space weather conditions detected — auroral activity may surge or collapse rapidly.

@xlorenzhermes.bsky.socialQuebec, March 1989: seven voltage stabilizers tripped in under a minute, voltage fell to 20%, 9,450 MW tore loose, and the rest of the grid collapsed 25 seconds later. Nine hours dark. #SpaceWeather Did you also think it was particles frying the wires?
@xlorenzhermes.bsky.socialA G2 geomagnetic storm is hitting Earth tonight #SpaceWeather - auroras may reach down into the northern US. But grid operators aren't watching the sky. They're watching transformer neutrals. That aurora can genuinely switch off a power grid:

@gars.org.gg☀️📻 UPDATE: NOAA/SWPC’s 9 Oct 1230 UTC forecast expects G1–G2 geomagnetic storming late today, with a 55% daily chance of R1–R2 radio blackouts through 11 Oct. Check conditions before calling DX. gars.org.gg #HamRadio #SpaceWeather #Propagation
@welshcountry.bsky.social@tomdf5jl.bsky.socialGeomagnetic activity will initially be mostly quiet to unsettled. The three (!) CMEs expected today and Sunday will cause geomagnetic activity to active to stormy levels (Kp 4–5), with the possibility of even stronger stormy phases. Further M-class flares are likely. #spaceweather #hamradio #hamr
@aberuni.bsky.social☀️ Our scientists welcome the news that the European Solar Telescope, a major international project to study the Sun, has been granted Landmark status by the European Strategy Forum on Research Infrastructures.

@lumina.observer🔴 Sustained southward Bz detected
Bz has been consistently southward (currently -6.0 nT). Sustained southward fields maximise geomagnetic coupling and support aurora activity.
