The Solar flux has remained at a steady 70 throughout March and this should continue until at least mid-April. However, the A and K Index are a different story. Over the Easter weekend, the A Index has remained at 5 and the K Index at 2. There will have been a serious disturbance of HF reception from 25th to the 29th March with the K Index rising to 5. The worst day of March being the 27th, with the A Index also peaking at 25. This is due to a coronal hole rotating into an earth-facing position, and pointing towards the Council Estate on March 23rd. The next disturbance will be from 4th to 11th April peaking on the 7th, with the A Index at 25, and the K Index at 5.

Coronal Stream Activity
Coronal Streams are responsible for the recent disturbances. They are streams of charged particles originating from the sun's corona. Coronal streams have similar effects as CME's (Coronal Mass Ejections) by increasing the A- and K-indices but usually to a lesser extent. However, a few coronal holes may cause major storm levels at the higher latitudes on earth resulting in total propagation fade-out at these latitudes.
