Any particular effects on us here on Earth? Mainly auroras, I assume?

From TFA >Impacts to our technology from a G3 storm are usually minimal. However, a G3 storm has the potential to drive the aurora further away from its normal polar residence, and if other factors come together, the aurora might be seen over portions of Pennsylvania, Iowa, to northern Oregon.

G 3 Strong Power systems: Voltage corrections may be required, false alarms triggered on some protection devices. 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.).

  I once heard the GS can bring the electrical grid down and in that, case it could take a lot (like months) of time to restore it. Is that possible or is that uninformed apocalyptic propaganda ?

    > Is that possible or is that uninformed apocalyptic propaganda ? I’m very far from an expert in this field, but yes, it’s possible. Super unlikely, but possible. What would happen that would take months is that if there was a significant enough voltage fluctuation do to the GS, it could damage transformers, substations, disconnects, and in the slimmest of chances, power plants too. For these large scale electrical grid components, there’s only so many spares around and it takes a while to build in significant quantity, so if there was mass destruction of grid attached equipment, yes, it might lead to a multi-month recovery time.

When I was working on a cable company it affects some of the satellite channels and we always get advance notification of this events. So we always monitor earth storm and sun storms :D

There were very faint auroras visible from Helsinki last night. Which is somewhat uncommon this far south. If the G3 storm hits Earth tonight (low chance), then there might be bright auroras. In the surprise storm from a few weeks ago, they said some auroras could be seen as far south as Pennsylvania.

  It's cloudy as hell today. I doubt we'll be seeing anything sadly.
