Summary: Calibrated LGR, knocked pepperweed down around 2nd tower.

July 9 2009 sherman island

lgr is running at 132 torr; mirror time is about 16 micoseconds..methane level is 1830 ppb, like twitchell..

calibrating lgr

precal 1994 ppb with cal gas equalt to 1976 ppb..time 0925 pst

post cal 1976 ppb....last cal was Jun 9.. we need to calibrate more often..the al drifted 20 ppb over th emonth

933 back running. field ch4 is 1840 ppb...pump is not pulling as hard. 189 torr

power crashed...joe swapped some power and now the pump is ok at 133 torr again.

there is waist high pepper weed in the enclosure next to the lower flux divergence study, whilethe pepper weed in the field is about ankle high. I took a ladder and knoced down the pepper weed in front of the lower flux divergence student..not perfect..

0952 back up and reunning
