, first observed by Galileo, normally follow an 11-year cycle. We are into a few years into (recorded) cycle number 24 but according to NASA it's looking rather underpowered
. Nobody is certain exactly what the consequences will be, but one distinct possibility is a cold period
; a previous low in solar activity, the Maunder minimum
, is correlated with a brief Little Ice Age
. Nobody really knows how this unusual solar weather pattern might interact with human-caused climate change. Previously
, albeit somewhat controversially.

The largest solar flare of the current solar cycle
shot off the sun earlier today. After the media latched on to what was predicted to be mostly a non-event last week (probably due to a NASA article released around the same time about a super spacestorm
) , it's not making as much news this time. But you should pay attention this time
. This could be the best and last chance for a lot of us farther south to see some auroras before the sun dives into solar minimum, assuming all the variables line up
correctly this time. I recommend watching the Solar Terrestrial Dispatch
, as it is a great all around resource for solar activity and auroras that includes live data and sightings reports by the general public. Unfortunately though, no doubt as word IS spreading, that site is being hammered again and may be quite slow.
