[ips-sf] IPS Summary Forecast for 03 September - issued 0358UT/03-Sep-2014

rwc rwc at ips.gov.au
Wed Sep 3 13:58:03 EST 2014


Flare activity is at low levels however there is an active region that
is set to rotate onto the sun in the next day or so that has been
consistently giving off large CMEs over the last few days. A large
filament lifted off from the sun at around 15UT on the 2nd of
September. Satellite imagery is now available to analyse the resultant
CME and initial modelling suggest an arrival time in the later half of
the 6th of September. Most of the material was ejected to the north so
this will be a glancing blow. Geomagnetic effects are expected to be
minor. The maximum useable frequency for HF communications is reduced
compare with monthly predicted values. This is expected to improve
over the next few days.
