sunspots
     
        1. Notional cause of an odd error.  "Why did the program
        suddenly turn the screen blue?"  "Sunspots, I guess."
     
        2. Also the cause of {bit rot} - from the myth that sunspots
        will increase {cosmic rays}, which can flip single bits in
        memory.  See also {phase of the moon}.
