Good Evening,
It started snowing last week before either net. It hasn't really
stopped since. After the first 24 inches there has been only a few
inches more. Power went out before midnight on Sunday. Around 8 AM it
came back on for a few minutes. Then it came back on again around 7
PM. The next day it was out for 12 hours.
Luckily, I had a thumb drive of journal papers and two fully charged
laptops. I spent quiet time next to the wood stove reading about new
techniques to analyze systems of PDEs, like the Navier-Stokes or Maxwell
equations. The techniques join neural networks to a finite element mesh
of governing equations. These constraints reduce the search space.
The sun is fairly blank but the flux rate remains elevated. There
have been some ejections from the back side but nothing headed toward
us. The auroral oval shows a medium level of activity, I expect noisy
signals with moderate QSB. However, there is nothing like checking
conditions yourself.
Please join us on (or near):
14050 kHz at 2200z Sunday (3 PM PDT Sunday)
7047 kHz at 2330z Monday (4:30 PM PDT Sunday)
73, Kevin. KD5ONS
