Occultation event with (14268) 00AK156, event index number 1426
Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/10/28 09:01:01 UTC
J2000 position of star is 10:26:40.9 -00:49:48
Equinox of date position of star is 10:28:00.0 -00:57:44
Star is 130 degrees from the moon. Moon is 37% illuminated.
Stellar brightness G=15.1, apparent brightess of occulting body is G=16.3
Use an exposure time of 0.45 seconds with the standard RECON-QHY system.
SNR of 5.6 per integration for unocculted signal
Expected flux drop is 75% with SNR of 4.2 for the occulted depth (per occulted point)
Apparent velocity is 29.5 km/sec on the sky relative to the star, or, 25.7 arcsec/hr.
Position angle of asteroid motion is 124.2 degrees
The recommended exposure time corresponds to 13.3 km per image.
The 1-sigma error in the time of the event is 1.2 seconds.
The 1-sigma cross-track error in the shadow position is 16.2 km.
The sky-plane scale is 4131.1 km/arcsec.
Diameter estimates:
46.8 km assuming a 5% albedo, aximum of 1.6 sec for a central chord
19.1 km assuming a 30% albedo, maximum of 0.6 sec for a central chord
Cross-track diameter of 57.5 km used for deployment plan.
