Space Weather Message Code: SUM10R
Serial Number: 737
Issue Time: 2022 May 20 0808 UTC

SUMMARY: 10cm Radio Burst
Begin Time: 2022 May 20 0743 UTC
Maximum Time: 2022 May 20 0744 UTC
End Time: 2022 May 20 0745 UTC
Duration: 2 minutes
Peak Flux: 210 sfu
Latest Penticton Noon Flux: 173 sfu

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

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: ALTTP2
Serial Number: 1138
Issue Time: 2022 May 19 1318 UTC

ALERT: Type II Radio Emission
Begin Time: 2022 May 19 1202 UTC
Estimated Velocity: 441 km/s

NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation

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: ALTXMF
Serial Number: 288
Issue Time: 2022 May 19 0721 UTC

ALERT: X-Ray Flux exceeded M5
