Space Weather
A major X1.1 solar flare from Earth-facing active region AR4479 peaked at 20h52 UT 30 June. A strong R3 radio blackout took out most HF radio communications across the mid and eastern Pacific and a large part of North and Central America.
A nine-minute type II radio emission was detected with velocity of 1,496 km/s. A Type IV radio emission was also detected. A 10cm radio burst was laso detected with a peak flux of 409 sfu. These all strongly indicate the release of a CME.
The solar flux is reducing and should be below M-level within the next 30 minutes. HF radio paths are slowly recovering.
