Sunspot Number, Recent Events, and a Classic American Song

Holy Cow! Get a load of this:

I hadn’t looked at any information on current “space weather” for some time now. So imagine my surprise and pleasure at seeing the figures for today: sunspot count (SN): 84, and solar-flux index (SFI): 115!!!!!

It really has been a crappy year, but with Solar Cycle 25 […]

The Twelve

No, I’m not referring to the horror novel by Justin Cronin, nor do I mean the twelve days of Christmas, the twelve disciples, or the Reginald Rose film “Twelve Angry Men.” I’m not talking about the Twelve Steps of Alcoholics Anonymous, Darryl F.

Not exactly heaven, but . . .

For component-level stuff, there’s Fry’s. It’s a chain similar to BestBuy except it caters to both the consumer as well as the professional repair and […]
