Space Weather Message Code: SUM10R
Serial Number: 788
Issue Time: 2024 Mar 25 0720 UTC
SUMMARY: 10cm Radio Burst
Begin Time: 2024 Mar 25 0643 UTC
Maximum Time: 2024 Mar 25 0643 UTC
End Time: 2024 Mar 25 0645 UTC
Duration: 2 minutes
Peak Flux: 310 sfu
Latest Penticton Noon Flux: 195 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.

SUMMARY: 10cm Radio Burst
Begin Time: 2024 Mar 23 0107 UTC
Maximum Time: 2024 Mar 23 0117 UTC
End Time: 2024 Mar 23 0213 UTC
Duration: 66 minutes
Peak Flux: 240 sfu
Latest Penticton Noon Flux: 198 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: 2024 Mar 11 0853 UTC
Estimated Velocity: 489 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.
Space Weather Message Code: SUM10R
Serial Number: 786
Issue Time: 2024 Mar 10 1807 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.
