Sol 343, November 13, 2019, and a weather swing is underway, either long term spring or short term regional change.
The air pressure is dropping fairly steadily, winds are high at 40-50 MPH, high temperature is rising a few degrees in the day time from the average highs of the past month, and even the lows have risen along with a strong increase in the average daily temperatures.
It will be interesting to read whether the vertical cycling can produce steady 24 hour and weekly patterns of pressure, wind speed, and temperature swings caused by local influence, or, perhaps the distant Southern hemisphere is capable of distant southern winter weather control of the equatorial belt.
The images returned for 342 show the arm and scoop are being lowered towards the right side contact with the tube yet remain above the ground surface.
The lowering seems to be about 1 cm between 339 and 342. Not much change in the scoop surface appearance and ground area where lighted.
They may be in progress of another attempt to hammer into the obstruction with pressure applied from the scoop body.
Rising temperatures of only a few degrees, could that be a reason for the new motion? Overall lifetime of the machinery probably is a more motivational reasoning.
