Yes, I could still see it when it was below (west of) zeta 
Tau and actually was still able to see it as it passed over a 
bright vertical pair that I thought later, when I got home and 
got my sky atlas, were mu and eta Gem (although I can't seem 
to get a lock on them in Brian's photo), right before it went 
behind the cirrus.  The bright star to its right in Brian's 
photo is beta Aur (El Nath).  The bright triplet at the eight
o'clock position from the nebula are lambda and phi1 and phi2
Ori. 

The nebula was really very bright.  It was very easily visible
at 1x (naked-eye) for three minutes, no problem, until it went 
behind the cirrus.  Could the separation cloud have been that 
bright and large?  How bright is it in Brian's photo?  He saw
it for only one minute, he said.  How long would the exhaust 
from the earlier Centaur burn have lasted?  In any case, I'm 
very glad that I got to see it, in spite of getting in place 
almost too late and way less than fully prepared.  Thank you 
again!

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.
