Mars Observers Should Continue to Monitor Dust Cloud Activity.


Hellas, the largest known Impact Basin in our Solar System, has its own weather and often generates high winds at the surface that produce dust clouds to overflow its boundaries. Such is probably the case below.


Images by Manos Kardasis show the South Polar Cap during Winter in the Southern hemisphere. The South Latitude of the Northern edge of the SPC is noted on each image set.

Dust Clouds in the Southern Hemisphere in Mid-Winter!

















Image Sets by Christophe Pellier show fine details in the classical features. Note also how the large cloud deck near the Morning limb retains its form and extent even after Mars rotated 36 degrees.

Many Clouds and North Polar Cap Activity Recorded in Early March as Ice is Transferred from Northern Polar Regions to Southern Polar Regions.

Stunning wide black stripe imaged on Jan. 6th, 2014 that lengthened through March 3rd as a narrower black stripe as the NPC ice continued to shrink uncovering a very dark surface.

Below is a cutaway of a map of the North Polar Cap at Ls = 90 by Chick Capen made from 1969 observations. See the dark figure extending into the NPC at longitude 60 degrees West that is in the same orientation as in the images. The map also shows Mare Boreum and Mare Acidalium to the South of the NPC exactly as shown in the images.

attendant circular shaped dust storm
