Brian,

 

I posted the below elsewhere. Images like yours are rough at best because humidity or seeing could yield the visible differences shown…

 

Go to https://www.aavso.org/ and enter alf Ori into the search box on the right and hit plot light curve. It might sound bad for lack of a better term but I would then uncheck the visual observations box on the chart. It looks like it has dimmed almost a magnitude since the start of November.

Here’s a side-by-side comparison: 2016 to last night.  The old shot was shorter exposure so I equalized exposure in Photoshop.  You can see that the field stars are identical in appearance.

 

A supernova would be the biggest event of our lifetimes.  Stay tuned.
