is SN2017eaw dimming? (Halifax)

Looked like a very clear night out east. I quickly submitted some requests for Burke-Gaffney. I noted that I did not have a job for NGC 6946. I wanted to check the supernova in the Fireworks galaxy. SN2017eaw appears to be fading.

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.
