Regions able to see the event: Europe,NMexico
Geocentric closest approach at 2025/11/19 03:08:13 UTC
J2000 position of star is 03:43:08.8 -04:25:19
Equinox of date position of star is 03:44:26.1 -04:20:29
Star is 151 degrees from the moon. Moon is 1% illuminated.
Stellar brightness G=14.5, apparent brightess of occulting body is G=14.7
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 9.5 per integration for unocculted signal
Expected flux drop is 53% with SNR of 5.0 for the occulted depth (per occulted point)
Apparent velocity is 16.3 km/sec on the sky relative to the star, or, 20.3 arcsec/hr.
Position angle of asteroid motion is 82.0 degrees
The recommended exposure time corresponds to 9.0 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 33.2 km.
The sky-plane scale is 2880.2 km/arcsec.
Diameter estimates:
60.0 km assuming a 5% albedo, aximum of 3.7 sec for a central chord
24.5 km assuming a 30% albedo, maximum of 1.5 sec for a central chord
Cross-track diameter of 52.1 km used for deployment plan.
