I got one night in V and plotted it with one night in Rc. V-R=0.12 at 
the maximum. That implies something in the A3 range. John Greaves said 
"This one looks to be about F0 for a giant from V-Ic, with 2MASS being 
slightly later at about F2 or so... I discount the Tycho2 colour in 
this instance as being too blue at an equivalent A5 for a giant."

I need to redo my photometry in Rc to get it all on the same plot. I'm 
also going to grab the TASS data and see how it all looks together.
