    Note: 
    Note:  The info on NC Cnc says that the minimum brightness for the secondary eclipse is 11.6 V.  From my reading last night, the secondary has a very shallow eclipse and the minimum is 11.15 V.

I'm also curious about the small hump I observed buying the secondary minimum.  I haven't been able to show this as an artifact.  It seems real.  Not sure what would cause it.
