Geomagnetic Alert 26-27 April

The solar wind flowing from a large coronal hole has intensified and the IPS has issued a geomagnetic alert. Minor storms are predicted for high latitudes (Tasmania, Southern New Zealand, Australian Antarctic Territories) tonight and unsettled conditions the day after (Friday 27th and Saturday 27th). Aurora can strike any time, although the best time to look to the south around local midnight.

However, the bright, just past full moon will significantly interfere with seeing any aurora, and dark sky sites have the best chance of seeing anything. IPS notice below.

A low latitude coronal hole effects in progress. Unsettled to
Active levels are expected 26-27 April. Minor storm levels still
possible.
