Hi guys,

 

it's cool to see how Mars South Polar Cap changed size in one month. I shot both these pictures with my usual setup that you can read below.

Planetary tilt = seasons

Thank you so much guys for the nice words grin.gif

 

Yes the reduction of the polar cap is due to the beginning of summer in southern emisphere.

Nice images Daniele - watching spring to summer on Mars has been fun this year. I'm guessing if Venetia can't tell the difference between seasons and climate change, they will rather struggle with the finer details of carbon cycle changes and consequent growing impacts on economy, environment and society. Of course, astonishingly, we can't control the seasons on Earth or Mars lol.gif , but we can control carbon emissions on Earth.

Daniele, a rough width measurement is 18.8-degrres on 17/09/2020 and regressed to 12.8-degrrees on 17-10-2020, or a loss of 6 degrees in cap width.  A typical width for those Mars dates would be 14.6 down to 9.5, or 5.2 degrees.  While it is a bit more loss it is not too far away for the standard deviation.   The south cap shrinking gets a little erratic during that season period.

Mike Malin ( http://www.msss.com/...0/spolar4years/ ) found in 1999 that the SPC was experiencing a sort of "global warming" and lasted unto after 2005.
