SUMMARY: X-ray Event exceeded X1
Begin Time: 2026-03-30 02:47 UTC
Maximum Time: 2026-03-30 03:19 UTC
End Time: 2026-03-30 03:44 UTC
X-ray Class: X1.5
Location: S27E42
NOAA Scale: R3 - Strong
Radio - Wide area blackout of HF (high frequency) radio communication for about an hour.

Issue Time: 2026-03-30 03:22 UTC
ALERT: Type II Radio Emission
Begin Time: 2026-03-30 03:00 UTC
Estimated Velocity: 1872 km/s
Description: Type II emissions occur in association with eruptions on the sun and typically indicate a coronal mass ejection is associated with a flare event.

Issue Time: 2026-03-30 03:07 UTC
ALERT: X-Ray Flux exceeded M5
Threshold Reached: 2026-03-30 03:06 UTC
NOAA Scale: R2 - Moderate

WARNING: Geomagnetic K-index of 4 expected
Valid From: 2026-03-29 15:46 UTC
Valid To: 2026-03-30 09:00 UTC
Warning Condition: Onset
Induced Currents - Weak power grid fluctuations can occur.
Aurora - Aurora may be visible at high latitudes such as Canada and Alaska.

WARNING: Geomagnetic K-index of 4 expected
Valid From: 2026-03-29 02:07 UTC
Valid To: 2026-03-29 12:00 UTC
Warning Condition: Onset
Induced Currents - Weak power grid fluctuations can occur.
Aurora - Aurora may be visible at high latitudes such as Canada and Alaska.

Issue Time: 2026-03-28 16:32 UTC
WATCH: Geomagnetic Storm Category G1 Predicted
Highest Storm Level Predicted by Day
Mar 29: None (Below G1) Mar 30: G1 (Minor) Mar 31: None (Below G1)
THIS SUPERSEDES ANY/ALL PRIOR WATCHES IN EFFECT
Comment: Isolated periods of G1 (Minor) geomagnetic storming are likely on 30 Mar due to CH HSS effects.
Induced Currents - Weak power grid fluctuations can occur.
Spacecraft - Minor impact on satellite operations possible.
Aurora - Aurora may be visible at high latitudes, i.e., northern tier of the U.S. such as northern Michigan and Maine.
