CME impact, X1.5 solar flare
Monday, 10 June 2024 17:16 UTC
The anticipated M9.3 coronal mass ejection has arrived at our planet. As expected, it looks like a glancing blow with the solar wind speed increasing to a modest 430km/s with the interplanetary magnetic field strength (Bt) increasing to about 15nT. A minor G1 geomagnetic storm watch is in effect for the remainder of today.
X1.5 solar flare
Departing sunspot region 3697 produced an X1.5 solar flare (R3-strong) at 11:08 UTC as she crossed the west limb. The solar flare was eruptive but as is to be expected, the resulting coronal mass ejection is aimed west and not directed towards our planet.
