Regions able to see the event: SAmericaN,Senegal
Geocentric closest approach at 2025/10/10 03:07:25 UTC
J2000 position of star is 02:56:50.4 +15:17:35
Equinox of date position of star is 02:58:16.3 +15:23:44
Star is 14 degrees from the moon. Moon is 87% illuminated.
Stellar brightness G=12.8, apparent brightess of occulting body is G=14.4
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 12.6 per integration for unocculted signal
Expected flux drop is 82% with SNR of 10.4 for the occulted depth (per occulted point)
Apparent velocity is 14.1 km/sec on the sky relative to the star, or, 15.0 arcsec/hr.
Position angle of asteroid motion is 70.9 degrees
The recommended exposure time corresponds to 1.7 km per image.
The 1-sigma error in the time of the event is 1.2 seconds.
The 1-sigma cross-track error in the shadow position is 24.2 km.
The sky-plane scale is 3382.9 km/arcsec.
Diameter estimates:
89.9 km assuming a 5% albedo, maximum of 6.4 sec for a central chord
36.7 km assuming a 30% albedo, maximum of 2.6 sec for a central chord
Cross-track diameter of 74.3 km used for deployment plan.
