[ips-sf] SWS Summary Forecast for 07 July - issued 2333UT/06-Jul-2016 [SEC=UNCLASSIFIED]

[rwc]

Very low levels of solar activity have been observed over the last 24
hours. The effect of a corotating interaction region followed by a
likely effect of a coronal hole are expected to strengthen the solar
wind stream on 7 July. The coronal hole effect may keep the solar wind
stream strong on 8 and 9 July as well. Solar activity is expected to
stay at very low levels over the next three days (7, 8 and 9 July).
Geomagnetic activity stayed at quiet levels today (6 July). The effect
of the corotating interaction region and the high speed solar wind
stream from the coronal hole may raise the geomagnetic activity to
active levels with the possibility of isolated minor storm periods on
7 July. The effect of this coronal hole may keep geomagnetic activity
high at minor storm levels on 8 July and unsettled to active levels on
9 July. Mild to moderate MUF depressions were observed over the low
and mid latitude locations on UT day 6 July. Minor to moderate
depressions in MUFs and degradations in HF conditions are likely from
7 to 9 July due to continued very low levels of ionising radiation and
the possibility of rise in geomagnetic activity levels during this
period.
