Titan Occultation of 28 Sgr in 1989
JOA 2018, Vol. 8, No. 2, Page 6 Author(s): David W. Dunham et al.Abstract: In 1989 an occultation by Titan was observed across Europe by about 200 observers. Light curvesobtained at (mostly) professional observatories were analyzed and formed the subject of several papers detailing the atmosphere of Titan. Additionally there were almost 200 visual observations made of the event. However those observations did not appear in the IOTA records of occultations. In this paper we review what happened with this rare event, discuss the problems with the visual observations and what can be learnt from them, and make recommendations for observing similar events in the future.
