Space Weather Message Code: SUM10RSerial Number: 896Issue Time: 2025 Dec 27 0156 UTCSUMMARY: 10cm Radio BurstBegin Time: 2025 Dec 27 0144 UTCMaximum Time: 2025 Dec 27 0144 UTCEnd Time: 2025 Dec 27 0146 UTCDuration: 2 minutesPeak Flux: 190 sfuLatest Penticton Noon Flux: 166 sfuDescription: 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.
