Occultation event with (14268) 00AK156, event index number 3469
Regions able to see the event: Europe
Geocentric closest approach at 2026/03/20 01:41:37 UTC
J2000 position of star is 10:12:01.5 -05:15:17
Equinox of date position of star is 10:13:20.7 -05:23:06
Star is 143 degrees from the moon. Moon is 1% illuminated.
Stellar brightness G=16.6, apparent brightess of occulting body is G=15.6
Use an exposure time of 1.15 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 29% with SNR of 0.9 for the occulted depth (per occulted point)
Apparent velocity is 15.3 km/sec on the sky relative to the star, or, 17.2 arcsec/hr.
Position angle of asteroid motion is 114.8 degrees
The recommended exposure time corresponds to 17.6 km per image.
The 1-sigma error in the time of the event is 2.1 seconds.
The 1-sigma cross-track error in the shadow position is 22.0 km.
The sky-plane scale is 3192.0 km/arcsec.
Diameter estimates:
46.8 km assuming a 5% albedo, maximum of 3.1 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.
