Occultation event with (32496) 00WX182, event index number 4142
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/09/01 02:35:58 UTC
J2000 position of star is 05:53:43.7 +30:18:33
Equinox of date position of star is 05:55:26.6 +30:18:46
Star is 61 degrees from the moon. Moon is 83% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=16.1
Use an exposure time of 1.05 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 39% with SNR of 1.2 for the occulted depth (per occulted point)
Apparent velocity is 22.9 km/sec on the sky relative to the star, or, 20.4 arcsec/hr.
Position angle of asteroid motion is 64.9 degrees
The recommended exposure time corresponds to 24.0 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 22.2 km.
The sky-plane scale is 4043.3 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 1.0 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
