The main body is 62.4 km wide, with a satellite between 6 and 60 km wide. We recommend an maximum exposure time around 100-200 ms. You can record 1 min after and before the event.
The maximum separation for the satellite’s position is ±300 km around the centrality. But we expect that the satellite should be close to the centrality within the path of the asteroid (±50 km) at the time of occultation. We encourage observation within and close to the centrality.
