Occultation event with (22014) 99XQ96, event index number 3212
Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2026/02/05 07:50:17 UTC
J2000 position of star is 11:31:29.2 -33:58:30
Equinox of date position of star is 11:32:46.5 -34:07:09
Star is 33 degrees from the moon. Moon is 87% illuminated.
Stellar brightness G=15.8, apparent brightess of occulting body is G=15.3
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 4.5 per integration for unocculted signal
Expected flux drop is 40% with SNR of 1.8 for the occulted depth (per occulted point)
Apparent velocity is 12.1 km/sec on the sky relative to the star, or, 13.7 arcsec/hr.
Position angle of asteroid motion is 53.0 degrees
The recommended exposure time corresponds to 9.7 km per image.
The 1-sigma error in the time of the event is 1.1 seconds.
The 1-sigma cross-track error in the shadow position is 38.1 km.
The sky-plane scale is 3171.4 km/arcsec.
Diameter estimates:
54.5 km assuming a 5% albedo, maximum of 4.5 sec for a central chord
22.2 km assuming a 30% albedo, maximum of 1.8 sec for a central chord
Cross-track diameter of 39.5 km used for deployment plan.
