WARNING: Geomagnetic K-index of 4 expected
Valid From: 2024-06-17 17:00 UTC
Valid To: 2024-06-17 22:00 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.

SUMMARY: 10cm Radio Burst
Begin Time: 2024-06-17 10:44 UTC
Maximum Time: 2024-06-17 10:44 UTC
End Time: 2024-06-17 10:44 UTC
Duration: 1 minutes
Peak Flux: 290 sfu
Latest Penticton Noon Flux: 167 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: 2024-06-17 11:33 UTC
ALERT: Type II Radio Emission
Begin Time: 2024-06-17 11:00 UTC
Estimated Velocity: 411 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.
