Good Evening,
The sunny days melted snow, the other days built it back up. Overall
there has been a net loss. A doe and two fawns took advantage by eating
all the fallen lichen exposed in the area. They spent over an hour
cleaning up.
The sun has reawakened with a number of active sunspots. Auroral
activity is high too. One of these nights it will be clear enough in
Oregon for me to see them. I expect the bands will be unsettled
tomorrow with a variety of odd noises.
Please join us on (or near):
14050 kHz at 2200z Sunday (3 PM PDT Sunday)
7047 kHz at 0000z Monday (5 PM PDT Sunday)
73,
Kevin. KD5ONS
