Occultation event with (32496) 00WX182, event index number 4476
Regions able to see the event: Australia
Geocentric closest approach at 2026/10/24 18:30:41 UTC
J2000 position of star is 06:07:06.1 +33:49:57
Equinox of date position of star is 06:08:52.6 +33:49:39
Star is 78 degrees from the moon. Moon is 97% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=15.7
Use an exposure time of 1.05 seconds with the standard RECON-QHY system.
SNR of 5.8 per integration for unocculted signal
Expected flux drop is 49% with SNR of 2.9 for the occulted depth (per occulted point)
Apparent velocity is 11.3 km/sec on the sky relative to the star, or, 11.7 arcsec/hr.
Position angle of asteroid motion is 159.3 degrees
The recommended exposure time corresponds to 11.9 km per image.
The 1-sigma error in the time of the event is 2.3 seconds.
The 1-sigma cross-track error in the shadow position is 28.1 km.
The sky-plane scale is 3474.6 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 4.7 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
