Occultation event with (32496) 00WX182, event index number 4280
Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2026/09/21 08:23:15 UTC
J2000 position of star is 06:03:08.3 +31:31:47
Equinox of date position of star is 06:04:52.4 +31:31:37
Star is 155 degrees from the moon. Moon is 73% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=16.0
Use an exposure time of 1.10 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 37% with SNR of 1.1 for the occulted depth (per occulted point)
Apparent velocity is 15.6 km/sec on the sky relative to the star, or, 14.7 arcsec/hr.
Position angle of asteroid motion is 49.6 degrees
The recommended exposure time corresponds to 17.2 km per image.
The 1-sigma error in the time of the event is 2.3 seconds.
The 1-sigma cross-track error in the shadow position is 14.2 km.
The sky-plane scale is 3825.9 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
