_______________
"Extreme" and G3 are mutually-exclusive. G3 storms at worst cause minor voltage fluctuations in ground systems, with occasional false alert triggers. In space, it can cause minor surface charge buildup on satellites, and can have small, intermittent impacts on satellite navigation and HF radio transmission.

G 3StrongPower systems: Voltage corrections may be required, false alarms triggered on some protection devices.
Spacecraft operations: Surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems.
Other systems: Intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon (typically 50° geomagnetic lat.).		Kp = 7200 per cycle
(130 days per cycle)

If that is 1800 UTC is 6 pm normal UK time, 7 pm on daylight silliness time and it is now just about 8 pm in the UK/Ireland now so I think we can mark everyone "safe" for now, unless it is supposed to hit tomorrow or something.

OK thanks, I didn't realize that hopefully everything will be fine as a G3 but it isn't an "X" super-flare either.

Ayup.

Somebody call me when it's X rated.

Actually, flares and geomagnetic storms are different. Think of a "storm" in terms of an eruption, sort of like a volcano, an event that has duration, whereas a flare is more of an explosion, a single-point event. Storms go from G1 through G5. Flares go from C to M to X.

Thanks, I was obviously confusing these; I understand which is which now.

This COULD BE SERIOUS...

We might end up having The Post Office go retrO, and having to lick our own stamps again!

The horror

Dang, you must be special! How did you get the Post Office to lick your stamps for you? They just hand me my roll and point to the door.

Yes! Old Jedi mind tricks. Postal workers and Ewok’s are similar in many ways.
