In this paper, page 7 (160 of the Journal), Fig 3, there is a particularly amusing (not to the authors!) caption:
"... On April 1 of year 2 in the $S_0$ experiment, the computer was hit by a cosmic ray or some other disturbance which caused improper numbers to be stored in the ground temperature array."
Note that the temperature array they are referring to is NOT a physical probe; the entire experiment was done numerically on what's probably a room sized computer for the duration of at least a year. The authors even plot a dashed corrected curve in the figure to try and account for this.
Are there any other documented cases of numerical errors arising from physical phenomena affecting older computers? I'm aware of stuff like the Pentium FDIV bug and the collection from this question but, I was wondering of examples more in line with the above caption from seemingly ridiculous sources like cosmic rays?
