Occultation event with (16560) Daitor, event index number 4161
Regions able to see the event: Europe
Geocentric closest approach at 2026/09/03 02:22:19 UTC
J2000 position of star is 05:33:52.7 +16:11:41
Equinox of date position of star is 05:35:25.0 +16:12:40
Star is 32 degrees from the moon. Moon is 64% illuminated.
Stellar brightness G=14.5, apparent brightess of occulting body is G=16.5
Use an exposure time of 0.50 seconds with the standard RECON-QHY system.
SNR of 10.0 per integration for unocculted signal
Expected flux drop is 86% with SNR of 8.6 for the occulted depth (per occulted point)
Apparent velocity is 18.5 km/sec on the sky relative to the star, or, 17.0 arcsec/hr.
Position angle of asteroid motion is 88.3 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 25.0 km.
The sky-plane scale is 3920.1 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 2.3 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 0.9 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
