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.
