I’m a ham operator and all of us in the worldwide community of amateur radio are sad because of a very low sunspot number lately. Today it is 13. The people on HF frequencies can’t use the ionosphere layer to reflect their RF signal very well. The general term for this phenomena is called Radio Propagation. Many factors are involved and the Sunspot Number is important. The higher the number, the more ionized this layer becomes, the more reflection of radio waves.
I’ve been reading about the L band we use to receive Outernet. It too is moderately affected by solar weather, So if you have noticed your SNR is a bit low the last few days, I would think the low sunspot number may be a big factor. Here is a reference: http://www.sws.bom.gov.au/Educational/1/3/2
Do a find on L-band (no spaces). BTW the Ku band is not affected by sunspots.
