Occultation event with (32496) 00WX182, event index number 4119
Regions able to see the event: Europe
Geocentric closest approach at 2026/08/29 04:22:52 UTC
J2000 position of star is 05:52:01.5 +30:08:30
Equinox of date position of star is 05:53:44.1 +30:08:47
Star is 100 degrees from the moon. Moon is 99% illuminated.
Stellar brightness G=15.3, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.50 seconds with the standard RECON-QHY system.
SNR of 5.4 per integration for unocculted signal
Expected flux drop is 68% with SNR of 3.7 for the occulted depth (per occulted point)
Apparent velocity is 23.9 km/sec on the sky relative to the star, or, 21.1 arcsec/hr.
Position angle of asteroid motion is 66.2 degrees
The recommended exposure time corresponds to 11.9 km per image.
The 1-sigma error in the time of the event is 1.3 seconds.
The 1-sigma cross-track error in the shadow position is 22.8 km.
The sky-plane scale is 4073.2 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 2.2 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 0.9 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
