Moderate M5.9 solar flare erupted from decaying Actve Region 1762 at 22:49 UTC on June 7, 2013. The event started at 22:11 UTC and ended at 23:04 UTC. This eruption hurled Coronal Mass Ejection (CME) into space, but considering the location of eruption, the plasma cloud was directed away from Earth.
This event was assiciated with R2 (Moderate) Radio Blackout level on NOAA Radio Blackout scale. At R2 level limited blackout of HF radio communication on sunlit side are possible wih loss of radio contact for tens of minutes. Degradation of low-frequency navigation signals for tens of minutes is possible.
