Visual estimate. Princeton, NJ. Apr 08.1 UT. 9" refractor.
Divide difference between star A and B into five steps.
SN is 1 step below A, 4 steps above B. Magnitudes from
Thompson-Bryan [m(B) = 11.9] and CCD photometry (Richmond,
private communication ;-) [m(A) = 11.4].
If m(A) = 11.4 and m(B) = 11.9, --> m(SN) ~ 11.5.

p.s. Who says professionals don't get out in the cold? :-)
p.p.s. An Astroscan just won't make it in these NJ skies.
