Cleared roughly 8-inches of snow from the roof this afternoon to allow both scopes to operate without dragging dome parts through the drifts. The fan (?) in the white computer in the chart room (furthest from the door) made a squealing noise for about 10 minutes in the middle of the night before stopping on it's own. It looks to still be running despite the noise. No other problems. |

It wasn't terribly cold last night, so I don't blame ice and snow. It more seems like one of the motors isn't functioning. The c/b's are good. Could there be something else to check? |
