Weather: Mostly cloudy today, with afternoon rain showers. Cool and windy again. It should be less cloudy tomorrow, but cooler. 

Tasking:

• The morning data check revealed that no QC table was generated today. The 18-00 UTC table from yesterday showed some NA's across all data on several towers, but not on all towers. Further inspection showed that data dropped out as early as ~2030 CST at lconv and ~2300 at rel, which brought down the Ubiquity network and ended all data transmission. This was clearly another power failure, as yesterday was a completely cloudy day. Plotting battery voltage and Icharge over the last 4 days shows a pattern of subdued charging during the day on these cloudy days and battery voltages dropping to 11.6 V before the data drops out at night. This is consistent with what we saw before the last power failure. The decision has been made to stop streaming data in real-time over the Ubiquities in favor of periodic data transmissions (every 3 hours).   
• No other issues were noted at this time.

There will be no IOP tonight.
