Occultation event with (24451) 00QS104, event index number 4712
Regions able to see the event: SMexico
Geocentric closest approach at 2026/11/16 05:07:08 UTC
J2000 position of star is 04:59:24.7 +41:32:21
Equinox of date position of star is 05:01:18.1 +41:34:39
Star is 127 degrees from the moon. Moon is 38% illuminated.
Stellar brightness G=15.3, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 5.6 per integration for unocculted signal
Expected flux drop is 49% with SNR of 2.7 for the occulted depth (per occulted point)
Apparent velocity is 16.3 km/sec on the sky relative to the star, or, 19.2 arcsec/hr.
Position angle of asteroid motion is 108.7 degrees
The recommended exposure time corresponds to 9.8 km per image.
The 1-sigma error in the time of the event is 0.1 seconds.
The 1-sigma cross-track error in the shadow position is 37.7 km.
The sky-plane scale is 3063.1 km/arcsec.
Diameter estimates:
51.3 km assuming a 5% albedo, maximum of 3.1 sec for a central chord
20.9 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 40.7 km used for deployment plan.
