These are some other details in regards to this story.  Some gracious science fan or astronomer made this video and commented with the details:

This illustration shows how the features in the spectrum of the light reflected from the bright spots is alternately red and blue shifted slightly compared to the average light of Ceres as it rotates. This very subtle effect has been measured from the ground using the HARPS spectrograph on the ESO 3.6-metre telescope at La Silla in Chile. The effect has been greatly exaggerated to make it visible and excludes the much brighter light coming from the rest of the disc of Ceres.

What do you think is causing these unusual changes?  In our opinion this is one of the most important astronomy stories in the last couple of years.
