134P on Kronk’s cometography

During 1983 September, Charles T. Kowal announced that an examination of photographic plates obtained during May with the 1.2-m Schmidt telescope at Palomar Observatory had revealed the appearance of a comet. The comet appeared as a diffuse, condensed trail on the three plates, which were obtained on May 8.23, 9.30, and 15.26. He estimated the magnitude as 16.

     At the end of September Marsden announced that asteroid 1983 JG, which had been discovered by Zdenka Vavrova (Klet' Observatory, Czech Republic) and previously published in Minor Planet Circular 8008, was actually identical to Kowal's comet. It appeared as a trail on an image obtained on May 14.95. Vavrova did not notice any diffuseness and reported a magnitude of 16.5. Zdenka Vavrova discovered first this object as  asteroid 1983 JG - turned out to be a periodic comet. It is known as a 134P/Kowal-Vávrová.  

Zdeňka Vávrová, (* 1945) is a Czech astronomer. She worked at Klet Observatory for 20 years. She discovered more than hundred minor planets and co-discovered 1 short periodic comet.  She worked at Klet Observatory as assistant of Antonín Mrkos during years 1975 - 1995. She worked on astrometry of asteroids and comets. Discoveries of 115 minor planets, with permanent number were credited to Zdenka Vávrová. One of her discoveries - asteroid 1983 JG - turned out to be a periodic comet. It is known as a 134P/Kowal-Vávrová.
