Occultation event with (2363) Cebriones, event index number 4618
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/09 07:21:45 UTC
J2000 position of star is 06:01:33.3 -06:26:41
Equinox of date position of star is 06:02:51.8 -06:26:46
Star is 126 degrees from the moon. Moon is 0% illuminated.
Stellar brightness G=13.1, apparent brightess of occulting body is G=14.5
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 9.9 per integration for unocculted signal
Expected flux drop is 78% with SNR of 7.8 for the occulted depth (per occulted point)
Apparent velocity is 16.9 km/sec on the sky relative to the star, or, 17.6 arcsec/hr.
Position angle of asteroid motion is 36.5 degrees
The recommended exposure time corresponds to 2.0 km per image.
The 1-sigma error in the time of the event is 1.3 seconds.
The 1-sigma cross-track error in the shadow position is 28.2 km.
The sky-plane scale is 3450.8 km/arcsec.
Diameter estimates:
93.8 km assuming a 5% albedo, maximum of 5.6 sec for a central chord
38.3 km assuming a 30% albedo, maximum of 2.3 sec for a central chord
Cross-track diameter of 96.0 km used for deployment plan.
