Regions able to see the event: Australia,SMexico
Geocentric closest approach at 2025/11/23 09:42:34 UTC
J2000 position of star is 03:06:26.1 +10:21:22
Equinox of date position of star is 03:07:50.4 +10:27:18
Star is 130 degrees from the moon. Moon is 9% illuminated.
Stellar brightness G=14.0, apparent brightess of occulting body is G=15.1
Use an exposure time of 0.25 seconds with the standard RECON-QHY system.
SNR of 9.0 per integration for unocculted signal
Expected flux drop is 74% with SNR of 6.6 for the occulted depth (per occulted point)
Apparent velocity is 15.9 km/sec on the sky relative to the star, or, 20.3 arcsec/hr.
Position angle of asteroid motion is 64.3 degrees
The recommended exposure time corresponds to 4.0 km per image.
The 1-sigma error in the time of the event is 1.0 seconds.
The 1-sigma cross-track error in the shadow position is 30.9 km.
The sky-plane scale is 2817.8 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, aximum of 2.9 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
