I'm quite worried as I'm on a transatlantic flight during this event, and there have been 6 solar eruptions with at least 4 CMEs (NOAA not up to date with the enlil spiral just yet). Here are a couple useful links I'm using to keep track of this event: NOAA Space Weather Prediction Center dashboards [1], FlightAware Flight Delays and Cancellations [2] and NOAA Global Positioning System Community Dashboard [3], Prof. Mathew Owens post [4]

Why are you worried? Not saying you're wrong to be worried, but I'm interested to know what the actual concern is.

My concern comes from my own naïveté. I don’t know enough about flying to know how concerned I should be.

Hearing there’s a storm that affects navigation is an eyebrow-raiser, especially when sitting at an airport gate like I am.

This site is also pretty good:

Looks promising so far.

Edit: damn those values are crazy. Gonna climb the mountain tonight. Fingers crossed for a clear sky

I came here to say the same. I will also be on a transatlantic flight on the 12th. Is there anything to be worried about with airplane electronics systems in flight, or is it more potentially on the side of "there might be flight delays"?

An airplane is a big closed conductive tube, not connected to the ground. There's nothing to worry about. I'd happily fly on those days.

As for why we worry about the storms on the ground - the main effects of Geomagnetic storms on the ground involve DC currents generated in power grids that span hundreds of miles, at the ends of those transmission lines, are transformers engineered to most efficiently use the transformer steel by almost pushing it to saturation, at which it rapidly loses the ability to contain more lines of flux. This saturation can then allow almost unlimited amounts of current to flow, turning the transformer into a space heater, connected to gigawatts of power. Things can then very rapidly get out of hand, circuits fault, opening lines, causing power to be diverted elsewhere, until the entire grid goes down.

No such issues can happen in an airframe.

I was trying to find stuff around Oct 2003 when the last event of this magnitude took place, but I wasn't able to find anything comparable. From what I can tell the forecast is more mild on the 12th UTC, so I wouldn't worry that much about that. I was worried in my case because my flight leaves pretty much at the apex of the geomagnetic storm.

I think we can expect delays, GPS being unresponsive, radio issues, and some control tower congestion & issues. Can't really comment with any more detail.

in link [4], what timezone is displayed? trying to figure out if I will be at the day or night side

[sukhavati]

all of them are UTC I believe, Prof. Mat answer to a question about the tz on the post replies

[idontwantthis]

Are you worried enough to not fly?
