The result of the only known good quality observations of September 18, 2017 Venus occultation by the Moon is presented in this article. This kind of observation can be done by students using a common camera, and the analysis can be designed as a mathematics and physics exercise. Several observations were carried out in Malang and Jakarta, but high quality data were obtained only in Jakarta. An analysis of the occultation geometry then showed that the shortest distance between Venus and the center of the Moon disk was 249 arcsec. We were also able to fit the occultation light curve with a simple geometric model using an additional correction factor (1 + sin2 ϕ) to compensate for the hill-shaped intensity variation in the Venus disk.
