Several small storms have been taking place at the edge of the south polar cap. These are seasonally normal, and detailed accounts of them were given in the 2003 and 2005 final reports which can be accessed from the section webpages in the part offering the chance to read past reports. In both cases the accounts are in the first part of the paper.
What is interesting is the degree of variability from year to year, and just now some dust has been seen near the remnant of the detached Novus Mons. This is unusual but not unprecedented. Observations will be welcome.
