    Note: 
    I captured more data on FQ Lyn last night.  This time I caught a minimum but it is now clear if this is the primary or secondary.  The var.astro site says the secondary eclipse is the same brightness as the maximum brightness.  I don't think this is correct.  I analyzed the data from ASAS-SN and it shows two well defined minima with the secondary eclipse just slightly brighter than the primary.  I suspect this is the primary eclipse I've caught but I may need more data to be sure.

In any case, the epoch shown on this site is just incorrect.   Feel free to email me for more info.
