Occultation event with (2363) Cebriones, event index number 4627
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/10 03:39:22 UTC
J2000 position of star is 06:01:18.8 -06:31:28
Equinox of date position of star is 06:02:37.3 -06:31:33
Star is 133 degrees from the moon. Moon is 1% illuminated.
Stellar brightness G=15.4, apparent brightess of occulting body is G=14.5
Use an exposure time of 1.40 seconds with the standard RECON-QHY system.
SNR of 8.1 per integration for unocculted signal
Expected flux drop is 30% with SNR of 2.4 for the occulted depth (per occulted point)
Apparent velocity is 17.0 km/sec on the sky relative to the star, or, 17.7 arcsec/hr.
Position angle of asteroid motion is 37.6 degrees
The recommended exposure time corresponds to 23.8 km per image.
The 1-sigma error in the time of the event is 1.2 seconds.
The 1-sigma cross-track error in the shadow position is 28.6 km.
The sky-plane scale is 3445.2 km/arcsec.
Diameter estimates:
93.8 km assuming a 5% albedo, maximum of 5.5 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.
