Snow flurries and telescope temperatures kept us closed until 00:20. At 22:37, we received an alarm about the SPIcam ion pump. It was an isolated message. When I went up to open again, the pressure had dropped to 1 e-11. I followed Bill's instructions in the email from Jan. 7 to restart the pump control, and after 3 minutes, the setpoint light remained dark and the pressure was 1 e-11 again. I called Bill at this point. He was able to determine that there was no immediate danger, and I monitored the temperature the remainder of the night without issue. After opening at 00:20, rest of the night was successful, with seeing 1u per 0.1 cubic feet. TELESCOPE STATUS Telescope drives operational. Current TCC version: 2.15.0 Current TUI version: 2.0.0
