There were six, low level M-class flares over the last day ending with
an X1.1 flare at 2308 UT. The X flare caused interruptions on lower
and middle HF bands for paths with ionospheric reflection points in
the West Pacific region. Moderate solar flare activity is expected,
making short-wave fadeouts likely. Moderate solar wind becoming
stronger 7 and 8 Jul due to coronal mass ejections on 3 and 4 Jul.
Geomagnetic conditions expected to be unsettled to active with
isolated minor storm periods on 7 and 8 Jul. High-frequency radio
communications normal or even enhanced slightly due to increased solar
output. Expect little effect on the ionosphere due to the CMEs.
