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


Go to 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.
