The satellite may be located around the primary body in a region of approximately +/- 30 km around it. We aim to build a mesh as dense as possible to cover both the primary and its satellite. The size of the primary is about 6.4 km and correspond to an occultation of 0.7 sec. The size of the satellite is mostly unknown (between 2 km and 5 km) and may correspond to an occultation of about 0.2-0.5 s. So please use a exposure of 100 ms maximum. Observations are requested at minimum 30 sec before and after the midtime. You can use the interactive map of the GaiaMoons page of the event to determine your local midtime.
