Yes, for suitable values of "recently".

How old are you?

If you're younger than say your mid-40s you probably won't remember the early 80s, which is the last time we had a solar maximum that really came to anything.

Solar activity rises and falls on an 11-year cycle, and right now we're experiencing quite a peak. The previous three, peaking in 2014, 2011, and 1989 were a bit of a bust.

There was a massive peak in 1979 and I can remember my dad showing me the aurora when I was about six or seven - it seemed to be present most nights over the winter. That was also around the time of the CB Radio craze, where atmospheric conditions were such that you could use "skip" - bouncing radio signals off the highly-charged ionosphere - to talk to people hundreds of miles away as if they were just down the road, even on the comparatively high frequencies that CB used. There was a bit of a peak in the late 80s, and some good RF propagation too, as well as some incredible aurora - although the big one I remember was in about the end of 1991, early 1992.

We had absolutely blistering hot summers followed by really cold and snowy winters, too, kind of like we're having at the moment.

If the solar cycles have a longer repeating cycle of intensity on the scale of a hundred years or so (and it looks a bit like they do) then the next solar maximum in about 2036 is going to be even bigger.
