M2.0 Solar Flare Recorded on Oct. 9 as Scientists Keep Watch

Researchers point to a sharp September surge that may signal a rare second peak in this solar cycle.

Overview

  • The Laboratory of Solar Astronomy at Russia’s Space Research Institute (IKI RAN) logged the flare around 15:30 MSK and rated it M2.0.
  • A separate, smaller C1.7 flare was recorded at 08:17 MSK the same day.
  • No significant Earth impacts have been reported from the Oct. 9 flares so far, and monitoring remains active.
  • Forecasters note that Earth‑directed disturbances could disrupt power systems, shortwave communications, and navigation, and broaden auroral visibility.
  • IKI RAN’s Sergey Bogachev previously reported a steep rise in solar activity in September, prompting watch for an unusual second cycle peak.
