Occultation event with (32475) 00SD234, event index number 4862
Regions able to see the event: Europe
Geocentric closest approach at 2026/11/24 22:58:45 UTC
J2000 position of star is 04:22:45.0 +52:15:42
Equinox of date position of star is 04:24:50.2 +52:19:22
Star is 26 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.4, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.90 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 42% with SNR of 1.3 for the occulted depth (per occulted point)
Apparent velocity is 19.0 km/sec on the sky relative to the star, or, 20.4 arcsec/hr.
Position angle of asteroid motion is 98.1 degrees
The recommended exposure time corresponds to 17.1 km per image.
The 1-sigma error in the time of the event is 0.8 seconds.
The 1-sigma cross-track error in the shadow position is 39.6 km.
The sky-plane scale is 3354.6 km/arcsec.
Diameter estimates:
41.9 km assuming a 5% albedo, maximum of 2.2 sec for a central chord
17.1 km assuming a 30% albedo, maximum of 0.9 sec for a central chord
Cross-track diameter of 38.4 km used for deployment plan.
