the Northern Lights
For some unknown reason, the Aurora Borealis seems to be more active during the spring equinox. You may have heard that solar activity and therefore aurora activity will approach a maximum in the year 2012. The solar minimum lasted longer and was quieter than predicted, to make matters worst the few times that there were big solar storms this past year the weather has not cooperated. The next Major Cycle 25 is expected in 2022 to 2027.
