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.

ALERT: Type IV Radio Emission
Begin Time: 2024-10-07 20:07 UTC
Description: Type IV emissions occur in association with major eruptions on the sun and are typically associated with strong coronal mass ejections and solar radiation storms.

ALERT: Type II Radio Emission
Begin Time: 2024-10-07 20:03 UTC
Estimated Velocity: 941 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.

End Time: 2024-10-07 19:31 UTC
X-ray Class: X2.1
Optical Class: 2b

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.
