Weather: Overcast, cold, and breezy today, with intermittent snow showers developing by about 1100 CST. Tomorrow is expected to be sunny and clear, but remain below freezing all day.

• There again were no obvious issues noted with the data today. 
• Due to the lack of sunshine today we decided to attempt to charge lconv and rel. We used the charger from the base trailer for the first time and had interesting results. It appeared to charge the batteries very quickly, from 35% charge to full within 10 minutes. The charger, multimeter, and Sunsaver all agreed that the batteries began drained and were fully (or at least mostly) charged within minutes. We found this hard to believe, but found nothing that suggested the batteries were not full. We left satisfied that the batteries had enough charge to make it through the night. 

There is no IOP tonight, but one is scheduled starting at 0200 on Wednesday morning.
