Occultation event with (32496) 00WX182, event index number 3923
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/08/02 04:25:03 UTC
J2000 position of star is 05:33:09.0 +28:39:29
Equinox of date position of star is 05:34:50.0 +28:40:30
Star is 93 degrees from the moon. Moon is 88% illuminated.
Stellar brightness G=15.7, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.40 seconds with the standard RECON-QHY system.
SNR of 3.3 per integration for unocculted signal
Expected flux drop is 61% with SNR of 2.0 for the occulted depth (per occulted point)
Apparent velocity is 32.5 km/sec on the sky relative to the star, or, 27.1 arcsec/hr.
Position angle of asteroid motion is 72.6 degrees
The recommended exposure time corresponds to 13.0 km per image.
The 1-sigma error in the time of the event is 0.9 seconds.
The 1-sigma cross-track error in the shadow position is 25.6 km.
The sky-plane scale is 4317.6 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 1.7 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 0.7 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
