Occultation event with (32496) 00WX182, event index number 4125
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/08/30 03:57:44 UTC
J2000 position of star is 05:52:36.3 +30:11:53
Equinox of date position of star is 05:54:19.0 +30:12:08
Star is 87 degrees from the moon. Moon is 96% illuminated.
Stellar brightness G=16.1, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 50% with SNR of 1.5 for the occulted depth (per occulted point)
Apparent velocity is 23.6 km/sec on the sky relative to the star, or, 20.9 arcsec/hr.
Position angle of asteroid motion is 65.8 degrees
The recommended exposure time corresponds to 14.1 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 22.9 km.
The sky-plane scale is 4063.2 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 2.3 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.
