1.) DISCUSSION OF SOLAR, SPACE & GEOMAGNETIC WEATHER CONDITIONS THAT CAN 
IMPACT MF & HF RADIO WAVE PROPAGATION IN A NEGATIVE MANNER-

I operated on 10 meters early this morning UTC using the digital mode JT65A 
using 25 watts. I saw lot's of single hop and double hop sporadic E (Es) and 
trans equatorial (TEP) radio wave propagation. I also saw some east-west F2 
layer radio wave propagation thanks to a rising background x-ray flux.

The daily sunspot number (DSSN) is 107. This is the second day in a row that 
the DSSN has been above 100 .

There are no significant impediments to good radio wave propagation on the 
HF bands as far as solar, space and geomagnetic weather.

On the medium frequency (MF) (300-3000 kc) band there is the normal 
absorption of RF signals in the D layer due to incoming cosmic rays from our 
star and also other stars outside of our solar system, also hard x-rays from 
our star. Also the background x-ray flux is running in the high C range so 
there is some additional moderate absorption of RF signals in the D layer.
