Abstract
A re-analysis of data near Cygnus X-3 in 1989–1990 using the Whipple Observatory atmospheric Cherenkov imaging telescope confirms the existence of the TeV J2032 + 4130 source first reported at a conference by the Crimean Astrophysical Observatory and confirmed independently by the HEGRA Collaboration in a referred publication. The significance of the Whipple observations at the a priori HEGRA position is 3.3σ. The peak signal was found at RA = 20 h 32 m, Dec = +41^∘ 33′. This is 0.6^∘ north of Cygnus X-3. The flux level (12% of the level of the Crab Nebula) is intermediate between that reported by the Crimean (100%) and HEGRA (3%) groups.
