Hi All,

 

As we start to approach the end of the Mars apparition, I thought it would probably be best to post the final series observations in a single thread.  In fact Mars is still well placed from my observatory at the moment, so hopefully I can continue to follow it for a while yet.  Over the past week we have had some excellent seeing conditions, and I have made two more Mars observations. 

 

14th April:  the main point of interest here is what looks like a bright white cloud over Olympus Mons.  Due to the increasingly northerly tilt of Mars, the Mare Sirenum and Mare Cimmerium are now located towards the top of the disk:

15th April: Similar views as on the previous day, seeing perhaps not quite as good but I could still use powers of x600 to see the fine details on the disk.  The Elysium region can be seen on the morning terminator- it is slightly brighter suggesting the presence of morning clouds over this large plain:

I will add more observations here as I make them.

 

Cheers,

-Paul

Observation made last night on 18th April- the only obvious feature is Mare Sirenum.  Solis Lacus on on the evening limb.

Hi all,

 

We've had a whole week of clear nights with some excellent seeing conditions.  I have been able to use high powers on my 12" Newtonian to continue to monitor the red planet.  Below are two recent observations showing the Solis Lacus and Mare Sirenum.  Mars' northerly tilt is continuing and so these southern hemisphere features are pushed towards the top of the disk.

 

White cloud activity is continuing and dusky shadings can be made out in the deserts to the north...

Thanks erick86 - if the planet’s visible, it must be observed!
