Off the top of my head, I don't think that sunspots in and of themselves

Having spent a portion of my life on the transmitter end of loran, I
understand its limitations...but I have to wonder...how often will solar
activity and precip static coincide when I am flying? The odds are pretty
good in my favor.

the problem with Lorans and precip static is that you get
precip static in the clouds pretty easily with Loran and IMC
is exactly when you need Loran to work.
