Occultation event with (16560) Daitor, event index number 4892
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/26 15:45:58 UTC
J2000 position of star is 05:30:50.2 +16:21:31
Equinox of date position of star is 05:32:23.4 +16:22:37
Star is 15 degrees from the moon. Moon is 94% illuminated.
Stellar brightness G=15.6, apparent brightess of occulting body is G=15.7
Use an exposure time of 0.65 seconds with the standard RECON-QHY system.
SNR of 4.8 per integration for unocculted signal
Expected flux drop is 52% with SNR of 2.5 for the occulted depth (per occulted point)
Apparent velocity is 16.5 km/sec on the sky relative to the star, or, 18.9 arcsec/hr.
Position angle of asteroid motion is 94.3 degrees
The recommended exposure time corresponds to 10.7 km per image.
The 1-sigma error in the time of the event is 0.4 seconds.
The 1-sigma cross-track error in the shadow position is 25.6 km.
The sky-plane scale is 3140.2 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 2.6 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
