Hi Everybody;


After a long and quiet period over the New Year the sun is waking up again…

NOAA just issued (see below) an onset warning for a G1 storm that is caused
by a coronal hole that allows the solar wind to escape. As this wind hits
earth the magnetic field starts to vibrate and it will create workable
propagation for the 40, 30 and 20m band.

The is a uptake of solar plasma which will also possible cause some
sporadic E on 6m and up.

The stream is forecasted to hit on the 20 of January and will last for at
least a few days according to the NOAA experts.

Conditions at the MDSR test station are still quiet but 10m has been up and
down in the last 4h.



*Current conditions at the MDSR test station:*

80m open S5

40m open S3

30m open S2

20m closed S2

15m closed S0

10m closed S0

All the best and 73;
