Generator/Electricity: At 0700 hrs the Hobbs meter read 2794.0 hrs and oil level was below the second mark on dipstick. A small amount of oil was added to bring the level to the second mark. Frequency 60Hz and voltage steady at 250 V.

Propane: North tank 83%; South tank 79%; Furnace tank 85%.

Water: The external tank is approximately 78% full. No transfer of water to internal tank, since tank was filled late the previous night.

GreenHab: No progress made.

Everest Rover: Returned from extended sortie about 1:20pm this afternoon. At about 2:00pm Anna Paulson and William Green from the Michigan team arrived with a new generator for the Everest. This was installed in Hanksville, and work continued until sunset. The Everest generator appears to be running normally, though needs some tuning.

ARES Rover: Now in Denver, Colarado.

Additional Activities: Mostly tidying up of the lower workshop area. A temporary solution to the kitchen sink odour problem was found in an air-permeable plug made out of a pair of activated carbon pads from the organic waste bin. These were soaked in disinfectant and bound by duct tape. When inserted into the drain vent they help control the odour from the waste pipe.

At approximately 1600 hrs while what seemed to be a storm coming in, sparks began to occur on the second floor of the Hab. These visual discharges occurred in two different locations. 1) At the entry point of the weather stations hab connections (just where they enter the hab) 2) At the receiver box of the radio telescope. What seemed to be electrostatic discharges ended after about a 10 minute period. There was worry of a fire and at the beginning of the sparking the power was cut off as this was thought to be associated in the early stages (though this was quickly found out to be not the case). Our recommendations are that the weather station and radio telescope inlet cables be grounded.
