A Stellar Occultation by the Nucleus of Comet 28P/Neujmin 1 – an Observational Account
JOA 2022, Vol. 12, No. 3, Page 10 Author(s): Stefano SposettiAbstract: An occultation of the nucleus of periodic comet 28P/Neujmin 1 visible from Europe took place on 2022 February 08. Five observing stations monitored the potential occultation, of which three stations recorded a positive event: two in Switzerland and one in Italy. For all three, the occultation appeared to be total with no significant dimming evident either before or after the main event. From the observational data it was possible to determine the approximate size of the nucleus at 18–20 km assuming it is spherical in shape. This article includes an account from the personal diary of one observer, Stefano Sposetti.
