Issue Time: 2025-02-20 09:09 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2025-02-20 04:44 UTC
Maximum Time: 2025-02-20 04:44 UTC
End Time: 2025-02-20 04:45 UTC
Duration: 1 minutes
Peak Flux: 200 sfu
Latest Penticton Noon Flux: 178 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.

Issue Time: 2025-02-20 08:37 UTC
ALERT: Type II Radio Emission
Begin Time: 2025-02-19 23:38 UTC
Estimated Velocity: 553 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: 2025-02-19 20:58 UTC
ALERT: Geomagnetic K-index of 4
Threshold Reached: 2025-02-19 20:55 UTC
Synoptic Period: 1800-2100 UTC

Active Warning: Yes
Induced Currents - Weak power grid fluctuations can occur.
Aurora - Aurora may be visible at high latitudes such as Canada and Alaska.

Issue Time: 2025-02-19 20:25 UTC
