In the Shadow of Jupiter – Europa Occults 10.5 mag Star
JOA 2023, Vol. 13, No. 2, Page 3 Author(s): Karl-Ludwig Bath, Martin Junius, Michael MushardtAbstract: On 2022 June 19, Jupiter's moon Europa occulted a 10.5 mag bright star. Normally, such an event would not be observable because of the large difference in brightness. But an extremely lucky coincidence made the observation possible anyway: Europa was just invisible in the shadow of Jupiter. The star, close to Jupiter, was thus obscured by the invisible Europa, for a whole of 100 seconds. Although there occurred still a number of problems, the observation was successful.
