Hi all:

 

I'm working on the AL Mars program and was out last night imaging. I'm not sure if maybe we caught a cloud or dust storm just north of the south polar cap?  the small white feature doesn't appear on the WinJupos ephemerides.

 

Any ideas?  Did anyone catch the same thing?

Thanks!

Looks like it could be a small dust cloud. You also captured the major one on the sunlit limb (notice how the westernmost part of Sinus Meridiani is missing).

Hi Mike,

 

It looks like a new dust storm to me, well done! waytogo.gif There are also two other possibilities, it may be a solar reflection from the edge of a Hellas CO2 glacier or even more remotely the result of an asteroid impact, we will find out in a day or two. I hope the HST imaging team is capturing all of this new planet wide activity so we can see up-close what is really happening on Mars.

 

Cheers, Dan cool.gif

I'm thinking a local dust activity. If it was a cloud it should stand out in blue light. I shot the area about an hour after you and my blue image shows nothing. Nice catch!

This is the season for dust storm activity on Mars.  There is a storm currently over the Opportunity rover (in Sinus Meridiani).  Our solar power dropped from 660 Watt-hours to 365 Watt-hours in just 2 days!  the other spot does look like a regional storm in Hellas.

What is the "OH NO" power level for Opportunity if the dust lingers?

This is dreary for us imagers (wanting to make pretty pictures). ‘Days away from a planetary (global) scale storm.’ Later on, ‘..lasts a few weeks to a few months. …should last a month or two but is unprecedented.’
