Occultation event with (32475) 00SD234, event index number 4524
Regions able to see the event: UAE
Geocentric closest approach at 2026/10/30 20:03:13 UTC
J2000 position of star is 04:42:04.2 +51:05:13
Equinox of date position of star is 04:44:08.6 +51:08:10
Star is 34 degrees from the moon. Moon is 72% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 3.9 per integration for unocculted signal
Expected flux drop is 61% with SNR of 2.4 for the occulted depth (per occulted point)
Apparent velocity is 17.0 km/sec on the sky relative to the star, or, 17.7 arcsec/hr.
Position angle of asteroid motion is 127.0 degrees
The recommended exposure time corresponds to 9.3 km per image.
The 1-sigma error in the time of the event is 0.5 seconds.
The 1-sigma cross-track error in the shadow position is 41.5 km.
The sky-plane scale is 3444.5 km/arcsec.
Diameter estimates:
41.9 km assuming a 5% albedo, maximum of 2.5 sec for a central chord
17.1 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 38.4 km used for deployment plan.
