Occultation event with (16560) Daitor, event index number 4336
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/10/01 08:02:22 UTC
J2000 position of star is 05:42:52.6 +16:12:43
Equinox of date position of star is 05:44:25.2 +16:13:22
Star is 21 degrees from the moon. Moon is 75% illuminated.
Stellar brightness G=12.1, apparent brightess of occulting body is G=16.3
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 20.5 per integration for unocculted signal
Expected flux drop is 98% with SNR of 20.1 for the occulted depth (per occulted point)
Apparent velocity is 5.4 km/sec on the sky relative to the star, or, 5.4 arcsec/hr.
Position angle of asteroid motion is 91.5 degrees
The recommended exposure time corresponds to 0.7 km per image.
The 1-sigma error in the time of the event is 1.3 seconds.
The 1-sigma cross-track error in the shadow position is 25.5 km.
The sky-plane scale is 3603.6 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 7.9 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 3.2 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
