Occultation event with (2363) Cebriones, event index number 4921
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/28 12:49:03 UTC
J2000 position of star is 05:54:17.3 -08:02:16
Equinox of date position of star is 05:55:34.9 -08:02:04
Star is 46 degrees from the moon. Moon is 79% illuminated.
Stellar brightness G=11.8, apparent brightess of occulting body is G=14.3
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 23.9 per integration for unocculted signal
Expected flux drop is 91% with SNR of 21.9 for the occulted depth (per occulted point)
Apparent velocity is 18.6 km/sec on the sky relative to the star, or, 20.0 arcsec/hr.
Position angle of asteroid motion is 58.8 degrees
The recommended exposure time corresponds to 2.2 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 34.6 km.
The sky-plane scale is 3351.1 km/arcsec.
Diameter estimates:
93.8 km assuming a 5% albedo, maximum of 5.0 sec for a central chord
38.3 km assuming a 30% albedo, maximum of 2.1 sec for a central chord
Cross-track diameter of 96.0 km used for deployment plan.
