Most of Alaska can expect lights tonight, with possible G1 storm conditions. Kp 5 possible both tonight and tomorrow night. Hopefully the weather is clear in your area. Date and time of this post is Feb 15, 2016 at 7 pm.
The most common question I get is, “what time will the lights be out?” & “when is the best time to start looking for lights?”. The answer is anytime it’s dark but typically in the middle of the night.
From NOAA Space Weather:The geomagnetic field is expected to be at (G1-Minor) storm
conditions early on day one (16 Feb), due to a possible late arrival of
the 11 Feb CME. Conditions should return to below G1 storm levels for
much of the remainder of day one, before returning to (G1-Minor) storm
conditions late on day two (17 Feb), due to the onset of a negative
polarity CH HSS. Day three (18 Feb) should see persistent CH HSS effects
in which elevated, but less than G1 conditions, are likely.
