Cloudy mid-afternoon, summer, on the plateau (UPDATED)

Mosaic of 8 NavCam images taken c. 15:40 local time on sol 1584. There've been quite a few cloudy early-mid summer afternoons like this of late (I hope to upload more examples later).

EDIT: I've added two more examples (from sol 1581 and 1577), both taken at the same time of day (15:00-15:30 hours).

Clouds at this location and time of year are not a surprise - the "aphelion cloud belt" is known to form in these tropical latitudes, and should last well into mid-summer here in the Nili/Jezero region. Evidently they can be seen later in the day as well - this example from about two months ago was taken after sunset.
