Occultation event with (54656) 00SX362, event index number 4937
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/29 06:33:05 UTC
J2000 position of star is 06:19:40.4 +01:55:11
Equinox of date position of star is 06:21:04.3 +01:54:23
Star is 42 degrees from the moon. Moon is 72% illuminated.
Stellar brightness G=12.6, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 14.6 per integration for unocculted signal
Expected flux drop is 96% with SNR of 14.0 for the occulted depth (per occulted point)
Apparent velocity is 16.1 km/sec on the sky relative to the star, or, 16.7 arcsec/hr.
Position angle of asteroid motion is 95.1 degrees
The recommended exposure time corresponds to 1.9 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 32.1 km.
The sky-plane scale is 3473.1 km/arcsec.
Diameter estimates:
44.9 km assuming a 5% albedo, maximum of 2.8 sec for a central chord
18.3 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 37.7 km used for deployment plan.
