ALERT: Type II Radio Emission
Begin Time: 2024 Mar 11 0853 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Mar 10 1530 UTC
Maximum Time: 2024 Mar 10 1532 UTC
End Time: 2024 Mar 10 1533 UTC
Duration: 3 minutes
Peak Flux: 150 sfu
Latest Penticton Noon Flux: 135 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.

Space Weather Message Code: SUM10R
Serial Number: 784
Issue Time: 2024 Feb 22 2341 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2024 Feb 22 2224 UTC
Maximum Time: 2024 Feb 22 2225 UTC
End Time: 2024 Feb 22 2235 UTC
Duration: 11 minutes
Peak Flux: 240 sfu
Latest Penticton Noon Flux: 173 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.
