Occultation event with (32496) 00WX182, event index number 4465
Regions able to see the event: Australia
Geocentric closest approach at 2026/10/23 17:05:49 UTC
J2000 position of star is 06:07:14.1 +33:45:19
Equinox of date position of star is 06:09:00.5 +33:45:00
Star is 93 degrees from the moon. Moon is 92% illuminated.
Stellar brightness G=16.8, apparent brightess of occulting body is G=15.7
Use an exposure time of 1.55 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 27% with SNR of 0.8 for the occulted depth (per occulted point)
Apparent velocity is 11.2 km/sec on the sky relative to the star, or, 11.5 arcsec/hr.
Position angle of asteroid motion is 161.6 degrees
The recommended exposure time corresponds to 17.3 km per image.
The 1-sigma error in the time of the event is 2.4 seconds.
The 1-sigma cross-track error in the shadow position is 27.0 km.
The sky-plane scale is 3484.6 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 4.8 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 2.0 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
