Note:
I think there is a problem with the ephemeris for this star.  The predicted ToM was 02/01/26, 02:52  UT.  This corresponds to JD 2461072.619444.  As you can see from the graph, I didn't catch the minimum because it was around 2 hours earlier.

I also tried using the AAVSO ephemeris computation for the star and it had a different, but also off, ToM.

I think the epoch or period for this star needs revising.  I will try to catch a true ToM at some time to aid in the epoch at least.
