I didn’t find this on the normal Dawn sites, but on a link from APOD. Note the weird shape of Ceres second-brightest spot.

This animation shows a sequence of images taken by NASA’s Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers), in its RC3 mapping orbit. The image resolution is 0.8 mile (1.3 kilometers) per pixel. In this closest-yet view, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. However, their exact nature remains unknown.

Its unfortunate space exploration is so slow, you’d hope those that propose a mission and get it accepted live to see the fruits of their labour

like “what are those dots exactly”?

When younger I would have agreed with you. I had to wait 12 years for Voyager 2 to pass Neptune.

But now it’s the approval/construction process that’s so slow.

The Square Kilometer Array (SKA) is going to be 19 years between proposal and first observations.
The James Webb Space Telescope (JWST) is going to be 22 years between gestation and launch.
The Laser Interferometer Space Antenna (LISA) is going to be at least 40 years between proposal and launch.

More detail.

May 26, 2015 – Dawn Reaching to Lower Altitudes

Dawn is following the carefully plotted trajectory around Ceres, maneuvering to prepare for its second mapping campaign next month. The probe’s mapping orbits are nearly circular, but during the flight from one to another, the intermediate orbits are more elliptical. Tonight Dawn’s complicated route will take it temporarily below the targeted mapping orbital altitude of 2,700 miles (4,400 kilometers). It will descend to 2,500 miles (4,100 kilometers) tomorrow before beginning another ascent.

On May 22 Dawn photographed Ceres to help the navigation team maintain a tight fix on its orbital position. Controllers used the opportunity to acquire bonus visible and infrared spectra.
