X9.0 solar flare! Strongest flare of Solar Cycle 25!

donderdag 3 oktober 2024 18:06 UTC

The solar flare was fairly impulsive but it still did cause an eruption which released solar material out in to interplanetary space. However, when we look at the coronagraph imagery from SOHO/LASCO courtesy of SEEDs we see a complex puzzle. The image is quite complicated with multiple eruptions going on, most notably an eruption to the north-west which likely comes from a filament eruption, an eruption to the north-west which might be far side related and a mostly southward eruption which likely is the X9 flare. However, we do see a clear full halo outline and a lot of you know what that means, there is an earth-directed coronal mass ejection inbound. We did not do any speed calculations yet but the coronal mass ejection does not look very fast purely based on the images we have right now. It is easy to get hyped but we are not expecting similar aurora like we had in May from this eruption but it will still be an event to look forward to.

Arrival times and Kp forecasts will be provided later once more data comes in but it's looking good for those who love aurora with now two coronal mass ejections heading towards Earth, the first one is expected to arrive at Earth in roughly 24 hours from now (late on 4 October).
