60 degrees is very bad. You need to have an under the tank heating source, preferably attached to a thermostat or dimmer - so you don't burn your snake either. I would get that done yesterday. You'll end up with one sick/dead snake if the temps stay that way for any length of time. The sooner the better!

Snakes require the heat to digest their meals, so no heat = no eat too. I would get your temps up to 92 hot side and 82 on the cool side. Measure temps with a digital thermometer and keep the temps stable!! The enviroment is so very important with an ectothermic animal.
