The SWS has issued a geomagnetic warning and aurora watch for 14-15 February
(UT) due to expected arrival of a CME from a recent solar flare. This is
expected to arrive early in the UT day on the 15th (which is the early evening
of the 15th Australian time) and may persist unlit shortly after midnight. The
SWS predicts active conditions. The Space Weather Prediction Service and NOAA
has Predicted a G1 storm on the evening of 15 February.
If these
geomagnetic events occur and result in aurora they could be seen from Tasmania
weather permitting. The Moon is new and will not interfere with aurora. Be
patient, as the activity may rise and fall of the magnetic polarity of the wind
may fluctuate significantly.
This event is unlikely to be as spectacular
as those in last year, but still worth a look as viewing conditions are good.
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, as well as bright proton arcs and "picket fences". A double
arc, blobs, and curtains were seen in Septembers aurora last despite the
moonlight.

predictions can be found at SkippySky.
A new
aurora camera is being installed at Campania, Tasmania. A live feed of the
images from this camera is still not available.
SUBJ: SWS GEOMAGNETIC
DISTURBANCE WARNING 18/01
ISSUED AT 0004UT/13 FEBRUARY 2018
BY THE
AUSTRALIAN SPACE FORECAST CENTRE.
From late 14 Feb to early 15 Feb
magnetic conditions may reach
active to minor storm levels due to expected
arrival of the CME
associated with the C1.5 flare peaked at 12/0135
UT.
INCREASED GEOMAGNETIC ACTIVITY EXPECTED
DUE TO CORONAL MASS
EJECTION
FROM 14-15 FEBRUARY

SWS AURORA WATCH
ISSUED AT 0024 UT ON 13 Feb 2018 by Space Weather
Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE
An active solar
region has rotated into a geoeffective position and
produced a coronal mass
ejections (CME). There is an increased chance
of auroral activity during the
period 14-17 Feb. Warnings and/or
alerts will follow if significant
geomagnetic activity occurs.
Our Aurora forecasting tool, located
at
http://www.sws.bom.gov.au/Aurora/3/1, may help to estimate
regions
from where aurora would be visible.
