Variable compstar on the nova V339 Del chart ?

We recently released a significant update to the backend systems for the AAVSO website. While most of the bugs introduced by this update have been fixed, there may still be problems we haven't fixed. If you run into a problem, please email

One of the compstars on the chart 12616GII is HIP101316 or 000-BCL-749.  According VSX is this a SR and variable between 7.05 - 7.3.   Why is this used as a compstar?

Hip 101316 is the comparison

Hip 101316 is the comparison marked '71' to the SE of the Nova. I am wondering has any recent V photometry been done on it.

I did use it on my last visual estimate. There is another comparison '71' to the NE of the nova can can be used instead.

000-BCL-749, the variable comp star you refer to has been removed as a como star.
