Activities

  • 2021-10-06 12:00 AK DT -- changed liquids in the geonor. 8 liters 60/40 mix & 1 bottle baby oil
    • Removed like 5.3 gallons
      • (Which means that last year's mix amount for antifreeze was more than necessary). 5.3 gallons removed = Freezing point of bucket around -25C
    • 8 liters mix = 72.7 cm liquid with freezing point @ -40
      • Realistically we only need the 60/40 mix to go to -40 by around April 1 so 72.7cm is extreme overkill and maybe I'll reduce the volumes down the road.
    • Re leveled stand, too.
  • Plugged in tipping bucket heater
  • Remove Forest Floor LI7200
  • Swap Tower LI7200 (But need to update the calibration info still)
  • Add an HDMI switch for monitor.
  • Swap out top 2 anemometers
