Occultation event with (14268) 00AK156, event index number 3451
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/03/17 02:11:47 UTC
J2000 position of star is 10:13:18.6 -05:23:48
Equinox of date position of star is 10:14:37.7 -05:31:38
Star is 163 degrees from the moon. Moon is 5% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.90 seconds with the standard RECON-QHY system.
SNR of 6.4 per integration for unocculted signal
Expected flux drop is 51% with SNR of 3.3 for the occulted depth (per occulted point)
Apparent velocity is 15.9 km/sec on the sky relative to the star, or, 18.0 arcsec/hr.
Position angle of asteroid motion is 113.3 degrees
The recommended exposure time corresponds to 14.3 km per image.
The 1-sigma error in the time of the event is 2.0 seconds.
The 1-sigma cross-track error in the shadow position is 23.1 km.
The sky-plane scale is 3179.4 km/arcsec.
Diameter estimates:
46.8 km assuming a 5% albedo, maximum of 2.9 sec for a central chord
19.1 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 57.5 km used for deployment plan.
