Occultation event with (14268) 00AK156, event index number 1014
Regions able to see the event: Australia
Geocentric closest approach at 2025/05/29 11:41:23 UTC
J2000 position of star is 08:29:37.5 +11:14:59
Equinox of date position of star is 08:31:01.0 +11:09:49
Star is 29 degrees from the moon. Moon is 8% illuminated.
Stellar brightness G=13.2, apparent brightess of occulting body is G=16.3
Use an exposure time of 0.13 seconds with the standard RECON-QHY system.
SNR of 10.0 per integration for unocculted signal
Expected flux drop is 94% with SNR of 9.4 for the occulted depth (per occulted point)
Apparent velocity is 27.8 km/sec on the sky relative to the star, or, 24.8 arcsec/hr.
Position angle of asteroid motion is 342.7 degrees
The recommended exposure time corresponds to 3.6 km per image.
The 1-sigma error in the time of the event is 1.4 seconds.
The 1-sigma cross-track error in the shadow position is 23.0 km.
The sky-plane scale is 4031.7 km/arcsec.
Diameter estimates:
46.6 km assuming a 5% albedo, aximum of 1.7 sec for a central chord
19.0 km assuming a 30% albedo, maximum of 0.7 sec for a central chord
Cross-track diameter of 46.6 km used for deployment plan.
