Weather:

	Observed Weather	AWS recorded weather
Time of Observation	1945	2013
Pressure / mB	986.2	985.6
Temperature / ‘C	+2.0	+1.6
Wind direction (magnetic)	090	080
Wind speed / knots	5	10

Work Done:

Removed faulty areovane (it was not giving wind speed and the direction was dubious).
Fitted new areovane. We found that this did not sit properly on the boom so put extra washers on the mounting to create a seal.
Installed new set (2 new boxes) of batteries because old ones where running down over night during the winter.
Mast was not raised due to negative accumulation. Stays were tightened.

Notes:

About 10 km from ice edge. There was a discontinuity in the snow/ice to the south of AWS, may be on an iceberg in next year or so. I recommend that it is moved to the south next year.
