ISSUED AT 0012 UT ON 29 Dec 2016 by Space Weather Services
FROM THE AUSTRALIAN SPACE FORECAST CENTRE

A recurrent equatorial coronal hole will soon reach geoeffective
location on the solar disk. The size of the current coronal hole is
relatively larger compared to its characteristics during the previous
rotation. The co-rotating interaction region and subsequent high speed
streams associated with the coronal hole is expected to affect Earth
from late 30 December. Auroras may be visible on the local nights of
30 and 31 December in Tasmania and possibly from the coastline of
Victoria.
