Occultation event with (4722) Agelaos, event index number 4679
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/14 04:36:19 UTC
J2000 position of star is 05:16:18.5 +24:51:35
Equinox of date position of star is 05:17:57.5 +24:53:15
Star is 154 degrees from the moon. Moon is 21% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=14.8
Use an exposure time of 0.95 seconds with the standard RECON-QHY system.
SNR of 4.7 per integration for unocculted signal
Expected flux drop is 27% with SNR of 1.3 for the occulted depth (per occulted point)
Apparent velocity is 13.2 km/sec on the sky relative to the star, or, 16.7 arcsec/hr.
Position angle of asteroid motion is 96.7 degrees
The recommended exposure time corresponds to 12.5 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 37.1 km.
The sky-plane scale is 2842.6 km/arcsec.
Diameter estimates:
57.3 km assuming a 5% albedo, maximum of 4.4 sec for a central chord
23.4 km assuming a 30% albedo, maximum of 1.8 sec for a central chord
Cross-track diameter of 50.4 km used for deployment plan.
