Progress of the regional dust storm on Mars - late June/early July

About this image

I noticed a light streak on the video feed when imaging Mars on 25 June from Canberra and Richard McKim quickly confirmed that the resulting images showed a dust strom in progress.

Here are some images showing changes from day to day. The image from the 30 June was particularly affacetd by poor seeing. Note the dust plume visible in the images from 25 and 27 June (arrowed), together with dust settling in the chasms of the Valles Marineris.  By 2nd July, the hemisphere looks quite dusty, and there is an odd light patch (arrowed) south of Meridiani Planum.
