This seems to match the images posted on spaceweather gallery by Bryan Tobias:
http://spaceweathergallery.com/indiv_upload.php?upload_id=109771&PHPSESSID=j4j2cb39b0i23v74cmvs52uth3

The star field has been identified as Taurus in the center, Gemini to
the top and Orion to the left. Aldebaran is at the bottom center. This
places these images also around 04:15UTC. As the payloads were
separated on time the cloud you saw must've been ejected around or
prior to the separation sequence.

This post on the NASA spaceflight forum suggests that this cloud may
have been from the Centaur spin up.

Interestingly the video three posts later in that thread shows the
Centaur de-spinning after separation of the 4th MMS.
