SUBJ: IPS AURORA WATCH
ISSUED AT 0638 UT ON 19 Aug 2015 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

A large Coronal Hole (CH 683) is located in the solar Northern
Hemisphere and is taking geoeffective position. A high speed solar
wind stream emanating from CH 683 is driving a Co-rotating Interaction
Region (CIR) and this will affect Earth's geomagnetic environment over
the next 1-2 days. Minor geomagnetic storms could occur in the high
latitude regions and possibly extend into the mid latitudes. The
aurora may be visible from the southern parts of Australia at the
local night hours on 19 and 20 August.
