[ips-sf] IPS Summary Forecast for 27 June - issued 0009UT/27-Jun-2015

[rwc]

Solar region 2371 is declining in complexity and size as it rotates
towards the west limb. There is still the small chance of M-class
flare activity from this region. Solar wind speeds are presently light
to moderate and are expected to increase during the latter half of the
UT day of 27 June with the anticipated arrival of a CME due around
18UT. Geomagnetic activity is expected to be initially quiet then
increasing towards the end of the UT day of 27 June with the
anticipated arrival of the CME. Minor storm periods are expected with
the arrival of this CME with major storm levels possible. Degraded HF
conditions are expected to continue into 27 and 28 June with the small
chance of SWFs. Energetic particle flux levels have crossed the event
threshold and are presently just above the S1 level. The elevated flux
levels are expected to decline slowly over the next 24 hours. Aurora
sightings may be possible for southern regions such as Tasmania should
the CME arrive early.
