SUMMARY: 10cm Radio Burst
Begin Time: 2026-03-30 02:54 UTC
Maximum Time: 2026-03-30 03:04 UTC
End Time: 2026-03-30 03:42 UTC
Duration: 48 minutes
Peak Flux: 1800 sfu
Latest Penticton Noon Flux: 158 sfu
Description: A 10cm radio burst indicates that the electromagnetic burst associated with a solar flare at the 10cm wavelength was double or greater than the initial 10cm radio background. This can be indicative of significant radio noise in association with a solar flare. This noise is generally short-lived but can cause interference for sensitive receivers including radar, GPS, and satellite communications.

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.

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.
