Regions able to see the event: Europe
Geocentric closest approach at 2025/11/28 22:58:50 UTC
J2000 position of star is 03:03:46.3 +10:02:42
Equinox of date position of star is 03:05:10.4 +10:08:42
Star is 61 degrees from the moon. Moon is 57% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=15.2
Use an exposure time of 0.80 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 27% with SNR of 0.8 for the occulted depth (per occulted point)
Apparent velocity is 14.9 km/sec on the sky relative to the star, or, 18.8 arcsec/hr.
Position angle of asteroid motion is 64.9 degrees
The recommended exposure time corresponds to 11.9 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 31.4 km.
The sky-plane scale is 2839.1 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, aximum of 3.1 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
