The media is reporting a large solar storm and saying it will upset GPS

Has anybody see any effects?
I won't be able to look at the data until I get home from work tonight,
but last evening I started measuring the sawtooth-corrected output of a
CNS2 clock vs. the PPS output of an Rb standard. Wondering if I'll see
any glitches... if so I'll report back here.
There was a major solar event in December, 2006 and at the time I was
monitoring GPS signal strength. I got a very noticeable glitch at the
time the blast hit the earth:

Unfortunately, I didn't have an appropriate PPS measurement going on at
the time.
