periodic comet in thesolar system discovered byRudolf Ferdinand Spitaler (Vienna ,Austria ) onNovember 17 ,1890 whilst attempting to observe Comet Zona (C/1890 V1).Spitaler, together with G. M. Searle, J. F. Tennant, and J. R. Hind, calculated orbits based on the observations, but despite predictions of a return in
1897 , it was lost and remained so for the next few decades.On
October 24 ,1993 , the comet was rediscovered by J. V. Scotti (Spacewatch ,Kitt Peak Observatory ,Arizona ,USA ), it was confirmed as Spitaler's comet whenBrian G. Marsden connected the 1890 and 1994 apparitions.External links
