Prochaska (UCSC): "In observing the field of Integral trigger 2486 with the PAIRITEL 1.3m we note a bright source near the center of the localization error circular. This source, at 13:24:03.027 +40:41:47 (J2000), is BD+41 2391 (=SAO 44596), is listed in the 2MASS catalogue with J=7.249, H=6.480 and Ks=6.289 mag and is of spectral type K2. Aside from the spatial coincidence, we have no other evidence connecting this source with the Integral trigger." This message may be cited.
