Occultation event with (32496) 00WX182, event index number 4225
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/09/12 08:10:14 UTC
J2000 position of star is 05:59:30.3 +30:58:16
Equinox of date position of star is 06:01:13.8 +30:58:15
Star is 95 degrees from the moon. Moon is 2% illuminated.
Stellar brightness G=16.3, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 44% with SNR of 1.4 for the occulted depth (per occulted point)
Apparent velocity is 18.8 km/sec on the sky relative to the star, or, 17.2 arcsec/hr.
Position angle of asteroid motion is 58.2 degrees
The recommended exposure time corresponds to 15.0 km per image.
The 1-sigma error in the time of the event is 1.7 seconds.
The 1-sigma cross-track error in the shadow position is 18.8 km.
The sky-plane scale is 3924.3 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 2.9 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
