Occultation event with (22014) 99XQ96, event index number 3725
Regions able to see the event: Australia
Geocentric closest approach at 2026/05/07 09:40:44 UTC
J2000 position of star is 10:54:19.2 -29:04:40
Equinox of date position of star is 10:55:34.7 -29:13:07
Star is 106 degrees from the moon. Moon is 73% illuminated.
Stellar brightness G=11.5, apparent brightess of occulting body is G=15.4
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 29.0 per integration for unocculted signal
Expected flux drop is 97% with SNR of 28.2 for the occulted depth (per occulted point)
Apparent velocity is 14.3 km/sec on the sky relative to the star, or, 16.1 arcsec/hr.
Position angle of asteroid motion is 0.6 degrees
The recommended exposure time corresponds to 1.7 km per image.
The 1-sigma error in the time of the event is 2.6 seconds.
The 1-sigma cross-track error in the shadow position is 16.7 km.
The sky-plane scale is 3181.9 km/arcsec.
Diameter estimates:
54.5 km assuming a 5% albedo, maximum of 3.8 sec for a central chord
22.2 km assuming a 30% albedo, maximum of 1.6 sec for a central chord
Cross-track diameter of 39.5 km used for deployment plan.
