Aurora Borealis Viewing
It appears as if the Aurora Borealis and Australis are only visible when
there is a significant irregular output from the Sun.
There is a local alert for people in the very Southern Oz States that
they may be able to see Aurora Australis and this information from
another source. Aurora USA - Aurora may be seen as low as New York to Wisconsin to Washington state.
ALERT: Geomagnetic K-index of 6
Threshold Reached: 2017 Apr 22 2359 UTC
Synoptic Period: 2100-2400 UTC
Active Warning: Yes
NOAA Scale: G2 – Moderate
NOAA Space Weather Scale descriptions can be found at
www.swpc.noaa.gov/noaa-scales-explanation
Potential Impacts: Area of impact primarily poleward of 55 degrees
Geomagnetic Latitude.
Induced Currents - Power grid fluctuations can occur. High-latitude
power systems may experience voltage alarms.
Spacecraft - Satellite orientation irregularities may occur; increased
drag on low Earth-orbit satellites is possible.
Radio - HF (high frequency) radio propagation can fade at higher latitudes.

It is beautiful and entrancing to view with the tunes, is easy to get lost in the colors
