19:15 UTC - Geomagnetic activity
Minor G1 geomagnetic storm (Kp5) Threshold Reached: 18:59 UTC
18:33 UTC - Solar flare
Moderate M1.31 flare from sunspot region 4055
CME arrival, G3 storm watch
A coronal mass ejection has arrived at our planet. This is the first of possibly two coronal mass ejections that were expected to arrive from filament eruptions on April 12 and 13. The minor G1 geomagnetic storm threshold has already been reached and the NOAA SWPC has a strong G3 geomagnetic storm watch in place for tomorrow, 16 April. Keep an eye on the data here on this website in the hours ahead. There is more action to come!
18:12 UTC - Radio Blackout
Minor R1 radio blackout in progress (≥M1 - current: M1.15)
17:45 UTC - Geomagnetic activity
Minor G1 geomagnetic storm (Kp5) Threshold Reached: 17:32 UTC
