The solar maximum refers to the sunspots which actually greatly assist High
Frequency propagation. We have been on a prolonged sunspot minimum (for
months there wasn't a single sunspot) and are finally starting to get sunspots
again, this time rotating the other direction meaning a new cycle. These
sunspots do not cause any loss of propagation in the SHF range (where GPS
signals reside.) A solar flare directly aimed at the earth is another
matter and that blacks out certain frequency ranges, but I am not sure if that
includes SHF or not at the moment.
I don't think that the telegraph lines were "shorted" as we would know the
term, however, I am sure that some electricity was induced in the long wires
during a large flare that would give that impression. Much like moving any
wire through an electro magnetic field. It probably made the sounders go
nuts as the power caused the magnets to operate on their own, but this is only
speculation.
Getting back to the original post, I will certainly use every means of
navigation at my disposal to fix position, but I also never want to be left with
a single method if it is at all avoidable. Celnav is a secondary method at
this point, but one that needs to be practiced in order to ensure
accuracy.

PS: Frank, the code to "laugh" is "hihi" which is a series of 12
dots. It is still used by morse code operators today among other
shorthands that are quite different from text messaging and the like on
computers. Sometimes I forget myself and mix them up but that's another
story.

According to the article that Gary posted (and confirmed by other sources),
the last solar maximum occurred in 2001. I wasn't using GPS at that time,
but I don't recall hearing anything about massive outages back then. Still,
this should reinforce the need to have a backup for any important system -
especially one as critical as navigation.
