Yep, sunspots are good, but if the sun throws a bunch of stuff at us (whats known as a coronal mass ejection) in our direction depending on the speed and density of it if the CME hits our atmosphere it can lead to HF blackouts

if you look at spaceweather on twitter or the NOAA https://www.swpc.noaa.gov/
