              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
The thunderstorms moved into the county before sunset and arrived at the site around the end of twilight.  For the rest of the night we had rain or high humidity or clouds or all three.
There was a site internet outage from about 20:15 to 20:30 local time, when the storm was passing over Tularosa but before it reached us.  After that connections were a little slow and spotty but no complete drops.
There wasn't much lightning by the time the storm reached us and I didn't close the valve for the NICFPS pump.  At 3 am I did close it since dome temperatures were dropping, but by 6 am the temperatures had leveled off and I really didn't think it would get cold enough to be a problem, so I re-opened the valve.
