It is quite interesting when you look at the variation over say some 30 years of data
mostly varying in Magnitude between 0.2 and 1, with infrequent outliers as high as nearly 0 and as low as 1.3 (now-ish), and the very consistent period of one year.
EDIT: given the one year periodicity
I'd be interested to know if the maxima/minima were in any way related to our orbital parameters/ position around The Sun and whether it coincided with perihelion / aphelion or .... ?
EDIT #2:
OK I just checked ROUGHLY from the graph data (and using a bit of visual interpolation over the years) which shows minimum apparent intensity around the start of each calender year, the same time as closest solar approach: perihelion,
or close enough. Who Knows, perhaps it's something on the star itself (logically more likely) rather than something "in between" that accounts for the one year period in the intensity / magnitude data?
