Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/11/05 07:20:00 UTC
J2000 position of star is 03:26:45.3 +03:21:01
Equinox of date position of star is 03:28:06.4 +03:26:21
Star is 22 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=13.3, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.14 seconds with the standard RECON-QHY system.
SNR of 9.9 per integration for unocculted signal
Expected flux drop is 89% with SNR of 8.8 for the occulted depth (per occulted point)
Apparent velocity is 17.3 km/sec on the sky relative to the star, or, 20.1 arcsec/hr.
Position angle of asteroid motion is 79.5 degrees
The recommended exposure time corresponds to 2.4 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 21.2 km.
The sky-plane scale is 3099.5 km/arcsec.
Diameter estimates:
42.9 km assuming a 5% albedo, aximum of 2.5 sec for a central chord
17.5 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 43.9 km used for deployment plan.
