Aurora Alert- Geomagnetic storm and Aurora reports NOW! (18 October 9:30 pm)

Launceston
 K-Index plot diagramThe Australian IPS has issued a geomagnetic alert for a G1 class storm NOW and the NOAA site has a G1 storm happening as well. Currently Velocity: 409 km/sec Bz: -7.0 nT Density = 12.0 p/cc. K index is currently 5 overall and 6 in the Launceston magnetometer. These conditions are promising. Unaided eye aurora have been reported from Launceston, Mt Wellington and Doges Ferry. In camera aurora have been reported from Tasmania (Eagle Hawk Neck and other sites) and South Australia. Unaided eye conditions may persist if the geomagnetic conditions hold.

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.
