34 at 5:30 AM.  Maybe 30 overnight for a short period because there was some ice on the puddles.  We were hoping for colder temperatures.  Warmed to 52.  Partly cloudy but the sun did make an appearance between 10:00 AM and 1:30 PM.

Into the woods by 8:45 AM.  R/O started at 10:00 AM and finished by 12:20 PM.  200 gallons in 140 minutes means 1.4 gallons/minute.  84 gallons/hour.  The R/O is rated at 125 gallons/hour.  Have to keep working on the controls to get the gallons/hour higher.  Sap out at just over 5 °Bx.  Finished cooking by 2:30 PM.  3 batches in the milk can.  Back at the farmhouse by 3:15 PM.  Actual cooking time was 5 hours.

Checked buckets at 1:30 PM.  Buckets had 1-2 quarts.  We plan to collect tomorrow.

Tonight also around 30.  Little cooler tomorrow.
