"The storm has seven appendages that stretch in all directions.
The overall cloud is about 700 to 800 miles across. It is spreading at a speed of about 35 mph and may become larger by the weekend." http://www.space.com/scienceastronomy/051028_mars_storm.html Rakhir |

Have these kinds of odd "extensions" been seen before in Martian dust storms? "There is an incredibly brilliant outbreak, perhaps yellow dust, between Margaritifer Sinus and Sinus Meridiani this morning, this developing from a minor yellow cloud just 24 hours ago. This feature is so bright that it is difficult to accurately image it without greatly underexposing the rest of the Martian features surrounding it. Note the (at least) seven (7) "fingers" or extensions that seem to radiate or spread outward from a large central area of unprecedented intensity. This odd area was first noted early this morning by Frank Melilo and Joel Warren and as it has rotated into view I believe that it has actually rapidly intensified in brightness. Hopefully west coast (USA) observers will get this as well.... I would appreciate the opinions and input of others, but honestly with the symmetry of the radiations emanating from this bright spot, I am not sure that we cannot rule out a catastrophic outflow, similar to that of eruption or even impact in nature. This does appear, because of the concentration in brilliance and the rapidity of development, to be extraordinary in nature." There is also an animation now on the ASO web site. |
