Strong Solar Flare Erupts from Sun

Quote

The Sun emitted a strong solar flare, peaking at 6:20 p.m. ET on Oct. 1, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X7.1 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

There's a high possibility that the Northern Lights will be seen as far south as where I am in Pennsylvania tonight (Thursday) and tomorrow night (Friday).

Northern Lights May Shine Above Pennsylvania, Much of Northern US Thursday & Friday Night – Weather Action (paweatheraction.com)

A forecast from the University of Alaska at Fairbanks has aurora being visible overhead late this evening as far south as the Mason-Dixon line, meaning all of PA will have a shot at seeing the auroras. Even if not visible directly overhead, we should be able to see them on the northern horizon. Here is that forecast for Thursday evening (10/3) at 11 PM.

The northern lights outlook for Friday evening looks very similar, although the maximum KP of 7 is expected to peak around 5-8 PM Friday. This means immediately after the sun goes down is when we expect aurora to be most visible. Here is NOAA’s Space Weather Prediction Center’s forecast for Friday evening. It looks exactly alike to Thursday night.

Has this been posted already?

This should produce aurora, but weather in the UK, at least, is forecast to be cloudy.

But the flare is big enough to interfere with power grids and satellites even if it can't be seen.
