Eclipsers can have flat bottomed minima when the eclipse is total.

However, the other minimum from you earlier observation run was at an
equal minimum magnitude to this one and had a quite "pointy" minimum
relative to this one.  I don't think it's possible for an eclipser to
have equal depth primary and secondary eclipses if one eclipse is total.
