Regions able to see the event: SAmericaN,SAfrica
Geocentric closest approach at 2026/02/23 03:45:52 UTC
J2000 position of star is 10:24:11.7 -06:16:55
Equinox of date position of star is 10:25:30.6 -06:24:54
Star is 114 degrees from the moon. Moon is 35% illuminated.
Stellar brightness G=14.0, apparent brightess of occulting body is G=15.5
Use an exposure time of 0.25 seconds with the standard RECON-QHY system.
SNR of 9.1 per integration for unocculted signal
Expected flux drop is 80% with SNR of 7.3 for the occulted depth (per occulted point)
Apparent velocity is 17.5 km/sec on the sky relative to the star, or, 20.0 arcsec/hr.
Position angle of asteroid motion is 103.2 degrees
The recommended exposure time corresponds to 4.4 km per image.
The 1-sigma error in the time of the event is 1.5 seconds.
The 1-sigma cross-track error in the shadow position is 27.9 km.
The sky-plane scale is 3145.2 km/arcsec.
Diameter estimates:
46.8 km assuming a 5% albedo, maximum of 2.7 sec for a central chord
19.1 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 57.5 km used for deployment plan.
