Comet 1936 II (Peltier) is the best candidate we found. Leslie C. Peltier, discovered 1936 II at mag. 9 on the evening of May 14, 1936. By early July it was naked-eye visible in Cassiopeia. The 3rd mag. comet with a 5 deg. tail,started to move swiftly southwards by months end, and reached maximum brightness (mag. about 2.9) around time of closest approach (12 million miles)to the Earth on August 4. Soon afterwards, it quickly became high in the sky for southern observers, still naked eye visible but fading. You can find a short article by John Bortle in Sky&Telescope, August 1986, p. 202. Here are osculating orbital elements for Epoch 1936 Jul. 11, from Brian Marsden's catalogue: Perihelion date = 1936 July 8.9552 Perihelion distance: q = 1.099868 AU e = 0.991775 Ascending Node = 134.2431 deg. Arg. perihelion = 148.4711 deg. Inclination = 78.5497 deg. Below we give an approximate ephmerides. Positions are given for 0000 UT.. Right ascencion and Declination are for 1950 Equinox. _r_ is the distance Comet-Sun in Astronimical Units. _delta_ is the distance Comet-Earth in Astronomical Units. _E_ is the enlongation from the Sun in degrees. Note that the m1 magnitudes are just guesses, and were made to fit the rough data available. date R.A.
