You can get them rated -55C -- +125C. If the rest of your board works
at -63C, this probably will, too. So long as you don't have a lot of
money hanging on it. So Ethan can probably take this board outside
for a while.
We usually put thermal controls (heaters and thermostats) on a board
if we actually think it's going to see temperatures that low. But if
you want to go for simple and you don't have too many exposed parts
you can attach a small resistor to the TO-99 as a heater that you can
run off of an unregulated voltage.
