Induced Currents - Power grid fluctuations can occur. High-latitude power systems may experience voltage alarms. Spacecraft - Satellite orientation irregularities may occur; increased drag on low Earth-orbit satellites is possible. Radio - HF (high frequency) radio propagation can fade at higher latitudes. Aurora - Aurora may be seen as low as New York to Wisconsin to Washington state. ------------------------------------------------------------------------------------------------------------------------------------------- MSG 2 - Date: 2026-03-18 09:03:34.557 Space Weather Message Code: SUM10R Serial Number: 902 Issue Time: 2026 Mar 18 0903 UTC SUMMARY: 10cm Radio Burst Begin Time: 2026 Mar 18 0833 UTC Maximum Time: 2026 Mar 18 0835 UTC End Time: 2026 Mar 18 0839 UTC Duration: 6 minutes Peak Flux: 229 sfu Latest Penticton Noon Flux: 111 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.
