Occultation event with (22014) 99XQ96, event index number 3582
Regions able to see the event: SAmericaS
Geocentric closest approach at 2026/04/06 01:39:20 UTC
J2000 position of star is 11:01:01.9 -32:25:58
Equinox of date position of star is 11:02:17.0 -32:34:28
Star is 63 degrees from the moon. Moon is 85% illuminated.
Stellar brightness G=15.2, apparent brightess of occulting body is G=15.1
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 6.2 per integration for unocculted signal
Expected flux drop is 49% with SNR of 3.0 for the occulted depth (per occulted point)
Apparent velocity is 16.4 km/sec on the sky relative to the star, or, 19.5 arcsec/hr.
Position angle of asteroid motion is 137.5 degrees
The recommended exposure time corresponds to 9.8 km per image.
The 1-sigma error in the time of the event is 2.3 seconds.
The 1-sigma cross-track error in the shadow position is 13.3 km.
The sky-plane scale is 3019.6 km/arcsec.
Diameter estimates:
54.5 km assuming a 5% albedo, maximum of 3.3 sec for a central chord
22.2 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 39.5 km used for deployment plan.
