Solar activity was low on 7 July. A C5.1 flare was observed at 0756 UT
from region 2561(S16W45). Solar wind stream got stronger today. The
solar wind speed gradually increased from 320 to 500 km/s during the
UT day 7 July. A coronal hole effect is likely to keep the solar wind
stream strong on 8 and possibly 9 July as well. Solar activity is
expected to stay at very low levels over the next three days (8, 9 and
10 July) with some possibility of isolated C-class activity.
Geomagnetic activity showed increases to unsettled to active levels
with isolated minor storm conditions on high latitudes on 7 July.
Nearly similar conditions may be expected on 8 July. Geomagnetic
conditions may gradually decline from 9 July. Mild to moderate MUF
depressions were observed on UT day 7 July. These MUF depressions seem
to have eventuated due to continued very low levels of ionising
radiation and rise in geomagnetic activity on this day. Minor to
moderate depressions in MUFs and degradations in HF conditions are
likely from 8 to 10 July due to continued very low levels of ionising
radiation and the possibility of continued rise in geomagnetic
activity levels during this period.
