Occultation event with (16560) Daitor, event index number 4548
Regions able to see the event: Australia
Geocentric closest approach at 2026/11/02 16:27:09 UTC
J2000 position of star is 05:40:45.9 +16:13:04
Equinox of date position of star is 05:42:18.8 +16:13:47
Star is 56 degrees from the moon. Moon is 41% illuminated.
Stellar brightness G=15.4, apparent brightess of occulting body is G=16.0
Use an exposure time of 1.15 seconds with the standard RECON-QHY system.
SNR of 8.3 per integration for unocculted signal
Expected flux drop is 63% with SNR of 5.2 for the occulted depth (per occulted point)
Apparent velocity is 9.2 km/sec on the sky relative to the star, or, 10.1 arcsec/hr.
Position angle of asteroid motion is 92.2 degrees
The recommended exposure time corresponds to 10.6 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 25.6 km.
The sky-plane scale is 3284.0 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, maximum of 4.7 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.
