That is a strange one!!!
I had a similar problem awhile back with the infrared satellite map. My map should have been the east coast but all of a sudden it started showing the west coast!
All this without any intervention from me what so ever! Then by the next day it was back to normal...also without any help from me.
I never did find fault on my end for that.. I just assumed there was some sort of database glitch on their part that recognized my station as west coast.
Only real answer...Gremlins! Seriously.. I hope whatever went wrong has corrected it's self. It's a bummer to diagnose the intermittent !
