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.
