Occultation event with (54656) 00SX362, event index number 4969
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/01 04:25:52 UTC
J2000 position of star is 06:18:48.5 +01:56:27
Equinox of date position of star is 06:20:12.4 +01:55:41
Star is 65 degrees from the moon. Moon is 51% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 3.7 per integration for unocculted signal
Expected flux drop is 56% with SNR of 2.1 for the occulted depth (per occulted point)
Apparent velocity is 16.7 km/sec on the sky relative to the star, or, 17.3 arcsec/hr.
Position angle of asteroid motion is 96.1 degrees
The recommended exposure time corresponds to 9.2 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 32.4 km.
The sky-plane scale is 3463.8 km/arcsec.
Diameter estimates:
44.9 km assuming a 5% albedo, maximum of 2.7 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.
