Aurora Watch 21-22 June 2015

An Aurora watch and a geomagnetic alert has been issued by the Australian  IPS for the 21st to 22nd  due to an anticipated impact from glancing blow from a Coronal Mass Ejection. The impact is expected at 19:00 AEST. This could translate into aurora at any time during the night time of the 21st to early morning 22nd and possibly evening of the 22nd   Aurora, if they flare up tonight, are likely to be seen in Tasmania, possibly Victoria, and if conditions are favourable in southern WA and southern South Australia.

Aurora can occur at any time after nightfall (although around midnight or just after seems to be common). Dark sky sites have the best chance of seeing anything, and always allow around 5 minutes for your eyes to become dark adapted.

As always look to the south for shifting red/green glows, beams have been reported consistently over the last few aurora and a large green “blob” has been seen.

The all sky aurora camera in Southern Tasmania at Cressy may be helpful (but has been acting up).

SUBJ: IPS GEOMAGNETIC DISTURBANCE WARNING 15/23
ISSUED AT 0454UT/19 JUNE 2015
BY THE AUSTRALIAN SPACE FORECAST CENTRE.

A coronal mass ejection has been observed in association with
a flare from region 2371 at 1736UT on 18 June. The majority of
the CME material appears primarily directed to the NE of the
sun, however further analysis suggests that the Earth will be
impacted by the edge of the CME around 09UT on 21 June. Minor
storm periods are expected following the impact with major storm
levels possible at high latitudes.

INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS EJECTION
FROM 21-22 JUNE 2015

GEOMAGNETIC ACTIVITY FORECAST
21 Jun:  Active to Minor Storm, with major storm periods possible at high
latitudes
22 Jun:  Mostly unsettled to active with minor storm periods possible at high
latitudes

SUBJ: IPS AURORA WATCH
ISSUED AT 0458 UT ON 19 Jun 2015 BY IPS RADIO AND SPACE SERVICES
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

A coronal mass ejection has been observed in association with a flare
from region 2371 at 1736UT on 18 June. The majority of the CME
material appears primarily directed to the NE of the sun, however
further analysis suggests that the Earth will be impacted by the edge
of the CME around 09UT on 21 June. Minor storm periods are expected
following the impact with major storm levels possible at high
latitudes, possibly resulting in visible auroras during local
nighttime hours. Aurora alerts will follow should favourable space
weather activity eventuate.
