SUMMARY: 10cm Radio Burst
Begin Time: 2024-10-09 15:44 UTC
Maximum Time: 2024-10-09 15:45 UTC
End Time: 2024-10-09 15:47 UTC
Duration: 3 minutes
Peak Flux: 2300 sfu
Latest Penticton Noon Flux: 225 sfu
Comment: Castelli U Burst
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: 2024-10-09 01:36 UTC
Maximum Time: 2024-10-09 02:03 UTC
End Time: 2024-10-09 04:00 UTC
Duration: 174 minutes
Peak Flux: 2700 sfu
Latest Penticton Noon Flux: 225 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: 2024-10-07 19:06 UTC
Maximum Time: 2024-10-07 19:07 UTC
End Time: 2024-10-07 19:10 UTC
Duration: 4 minutes
Peak Flux: 640 sfu
Latest Penticton Noon Flux: 265 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.
