I am fortunate to have some fairly consistent morning conditions,allowing a reasonable early overview of Mars.
Syrtis Major and Hellas are well seen.
Even at this resolution,it does appear that there may be two large dust clouds in Hellas.


It's only been just over a week since I've been able to start imaging Mars and with the planet so small and at associated reduced resolution,
I was not expecting to pick up any significant activity.
So my interest was pricked when I seemed to detect two large dust clouds in the giant Hellas impact basin
(+-7000km in diameter,and +-8km deep),which is above the famous prominent dark feature,Syrtis Major.
It was rewarding to have confirmation of this dust activity from images captured by the MARCI camera onboard the NASA Mars Reconaissance Orbiter on the same day.
My sincere thanks to Dr Bruce Cantor of Malin Space Science Systems for the MARCI images.
