Remember last November when NASA recorded the
biggest solar flare to date (well okay there have undoubtedly been larger flares, but this was the biggest one NASA's seen)? Now, I'm not making any predictions, but we've seen some
pretty decent sized flares in the last few days and it looks like there's another big gaggle of sunspots rounding the Sun's eastern limb in the next few days.
I've already seen two memory errors on two of my older servers (we saw a few in November as well) so if you're looking for a good excuse when things go really wrong for the next week or so you can blame it on sunspots!
(For the overly geeky the servers to which I refer are running non-parity RAM so a cosmic ray hit on the memory chips can flip the bit causing a parity error to pop up. Props to Dr. Ben the Astrophysicist and UNIX guru for providing that explanation lo those many years ago now.)
