For those of you working SDSSJ1238-03, I've come across a variable star
close to the target that you'll want to avoid using as a comp star.  The
location of the star is at RA 12 37 56.95, Dec -03 38 08.2  . The
unfiltered magnitude is about 15.8.

It looks like an RR Lyrae, and I've got a preliminary period of about 10
hours.  You can see the lightcurve at

As you can see, it would make a really poor comp star :-)

I have not found any reference to this star in Simbad, GCVS or  ROTSE.

Regards,

Bob Koff
