I found a few CCD comparison stars for TT Ari:

This one is from ASAS-3:
RA: 02:07:14.2   Dec: 15:19:48.3    V:11.829    Verr: 0.039   

Arne's .dat file is faint. These are the brightest stars I could fine.
Try to stay within 3 mags of TT Ari. So use the 14.6 star first and
switch to 15.2 if TT Ari gets fainter than  12.2.

RA: 02 06 49.0   Decl.: +15 17 00.1   V: 14.624   Verr: 0.017   B:
15.300   Berr: 0.040
RA: 02 06 49.8   Decl.: +15 20 05.5   V: 15.210   Verr: 0.042   B:
16.039   Berr: 0.065

I'm doing this from my laptop in a hotel room, without my usual tools.
So I'd appreciate it if someone else would double check these values.
