Occultation event with (14268) 00AK156, event index number 3592
Regions able to see the event: SAmericaS
Geocentric closest approach at 2026/04/07 06:17:48 UTC
J2000 position of star is 10:05:57.9 -04:22:49
Equinox of date position of star is 10:07:17.3 -04:30:33
Star is 98 degrees from the moon. Moon is 77% illuminated.
Stellar brightness G=13.5, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.17 seconds with the standard RECON-QHY system.
SNR of 9.9 per integration for unocculted signal
Expected flux drop is 90% with SNR of 8.9 for the occulted depth (per occulted point)
Apparent velocity is 10.3 km/sec on the sky relative to the star, or, 11.2 arcsec/hr.
Position angle of asteroid motion is 127.8 degrees
The recommended exposure time corresponds to 1.8 km per image.
The 1-sigma error in the time of the event is 3.5 seconds.
The 1-sigma cross-track error in the shadow position is 14.0 km.
The sky-plane scale is 3304.5 km/arcsec.
Diameter estimates:
46.8 km assuming a 5% albedo, maximum of 4.5 sec for a central chord
19.1 km assuming a 30% albedo, maximum of 1.9 sec for a central chord
Cross-track diameter of 57.5 km used for deployment plan.
