Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/11/10 03:01:15 UTC
J2000 position of star is 01:13:59.7 +04:50:54
Equinox of date position of star is 01:15:20.1 +04:59:05
Star is 93 degrees from the moon. Moon is 72% illuminated.
Stellar brightness G=15.5, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 6.2 per integration for unocculted signal
Expected flux drop is 53% with SNR of 3.3 for the occulted depth (per occulted point)
Apparent velocity is 15.7 km/sec on the sky relative to the star, or, 16.2 arcsec/hr.
Position angle of asteroid motion is 53.9 degrees
The recommended exposure time corresponds to 12.5 km per image.
The 1-sigma error in the time of the event is 0.9 seconds.
The 1-sigma cross-track error in the shadow position is 18.8 km.
The sky-plane scale is 3485.0 km/arcsec.
Diameter estimates:
56.0 km assuming a 5% albedo, aximum of 3.6 sec for a central chord
22.9 km assuming a 30% albedo, maximum of 1.5 sec for a central chord
Cross-track diameter of 50.8 km used for deployment plan.
