Space Weather

An M2.7 flare peaked at 09h19 UT from almost Earth-facing region AR4246. A minor R1 radio blackout affected eastern and southern Africa.

An M1.9 flare also erupted from AR4246 at 05h27 UT 13 Oct.

Increasing solar activity has increased noise on the HF bands. Conditions on HF are mostly "fair" at this time.
