SUBJ: IPS AURORA WATCH
ISSUED AT 0001 UT ON 02 Oct 2015 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

A transition region between slow solar wind and fast solar wind is
expected to arrive at Earth late today, 02 Oct, or during the first
half of 03 Oct. The arrival of this disturbance with subsequent fast
wind may trigger minor geomagnetic storms. The two massive CMEs
launched toward the west during 30 Sep are not Earthward directed but
a glancing blow is possible commencing late 03 Oct or early 04 Oct. A
significant geomagnetic storm might occur if the massive CMEs impact
Earth immediately following the arrival of the fast wind wind. Aurora
watchers located in Tasmania and southern Victoria should monitor
space weather conditions this weekend, just in case a geomagnetic
storm eventuates.
