Kallichore is a satellite of Jupiter and a flyby target of ESA’s mission JUICE!
Yücel Kılıç, Instituto de Astrofísica de Andalucía (IAA-CSIC), wrote on Planoccult on Mar 30:
Following a successful single-chord detection in December 2025, supported by HST astrometry and recent GTC observations, the prediction accuracy has significantly improved, making this event one of the best opportunities to obtain a multi-chord occultation before the JUICE flyby.
The occulted star has a magnitude of approximately G ~ 11.9, which is relatively favorable. However, the event remains technically challenging due to its low altitude (~10°) and short duration (~0.24 s).
We strongly encourage observers along and near the path to participate. Even negative observations are extremely valuable, as they help constrain the orbit and refine the shadow path.
