V1500 Cyg active or photometry issues?

I happened to look at the LCG on this old high amplitude nova, and saw what appears to be a time series set made on Sep 24. The variation in magnitude seems enormous and chaotic, between 15 and 19. Some of the observations vary by 2-3 magnitudes with the same time stamp, so it makes me somewhat suspicious of a data issue? Maybe someone more familiar with this star, could take a look and render an opinion on what might be going on here? Thanks!

I saw that too (on MNF) and was very surprised by the variation in magnitude.  

Rightly or wrongly I just assumed it to be in error.

Thank you for bringing this to my attention, Mike.

I have broght this to the attention of the observer so I'm sure it will be straightened out before long.
