Occultation event with (16560) Daitor, event index number 4553
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/03 04:24:35 UTC
J2000 position of star is 05:40:37.4 +16:13:08
Equinox of date position of star is 05:42:10.4 +16:13:52
Star is 63 degrees from the moon. Moon is 36% illuminated.
Stellar brightness G=16.8, apparent brightess of occulting body is G=16.0
Use an exposure time of 1.50 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 32% with SNR of 1.0 for the occulted depth (per occulted point)
Apparent velocity is 9.4 km/sec on the sky relative to the star, or, 10.3 arcsec/hr.
Position angle of asteroid motion is 92.3 degrees
The recommended exposure time corresponds to 14.1 km per image.
The 1-sigma error in the time of the event is 0.7 seconds.
The 1-sigma cross-track error in the shadow position is 25.7 km.
The sky-plane scale is 3280.0 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 4.6 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
