Occultation event with (32496) 00WX182, event index number 5055
Regions able to see the event: Europe
Geocentric closest approach at 2026/12/05 19:41:22 UTC
J2000 position of star is 05:48:35.8 +36:41:03
Equinox of date position of star is 05:50:25.4 +36:41:27
Star is 130 degrees from the moon. Moon is 10% illuminated.
Stellar brightness G=13.1, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 10.4 per integration for unocculted signal
Expected flux drop is 88% with SNR of 9.2 for the occulted depth (per occulted point)
Apparent velocity is 19.7 km/sec on the sky relative to the star, or, 22.1 arcsec/hr.
Position angle of asteroid motion is 111.5 degrees
The recommended exposure time corresponds to 2.4 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 37.7 km.
The sky-plane scale is 3212.0 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 2.7 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
