Propagation de Tad Cook, K7RA

[Artikelrobot]

Our sun is very quiet. The daily sunspot reading was 0 each day from January 29 through February 7. The last time we saw ten consecutive days with a sunspot number of 0 was way back on the other side of the solar cycle, from December 24, 1996 to January 3, 1997
