Weather: Sunny and clear all day. Sporadic breezy conditions and cool. 

Tasking:

• The morning data check showed the same few issues with EC150s as previous days, all of which seem likely to be due to wetness from rain/dew. 
• We picked up 3 batteries from Shaff Impliment this morning. Replaced lowest reading battery at each of lower convergence, upper convergence, and release towers. 
• Lastly, we dropped off the CSAT that we replaced on Saturday at the storage unit. This sensor is likely fine, but requires some adjustments through the EC-100 box.

There was discussion of a possible, very short IOP tonight, but PI's decided against it. The forecast looks very unfavorable for the next few days for any IOP's.
