MARCI weather report, April 22-28, 2019

For the past week on Mars, numerous local-scale dust storms of varied size occurred along the southern highlands — below 50° S. latitude. Looking to the northern hemisphere, dust-lifting activity was more sporadic. A couple of arcuate (bow-shaped) dust storms were spotted over the plains of Acidalia and Utopia near the beginning of the week. Poleward of this activity, the edge of the seasonal north polar ice cap continued its gradual retreat. [More at link, including video]
