Regions able to see the event: SAmericaN
Geocentric closest approach at 2025/08/05 09:30:57 UTC
J2000 position of star is 04:02:28.0 +11:41:07
Equinox of date position of star is 04:03:52.9 +11:45:18
Star is 151 degrees from the moon. Moon is 84% illuminated.
Stellar brightness G=12.7, apparent brightess of occulting body is G=15.9
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 13.4 per integration for unocculted signal
Expected flux drop is 95% with SNR of 12.7 for the occulted depth (per occulted point)
Apparent velocity is 20.1 km/sec on the sky relative to the star, or, 18.9 arcsec/hr.
Position angle of asteroid motion is 71.3 degrees
The recommended exposure time corresponds to 2.4 km per image.
The 1-sigma error in the time of the event is 1.6 seconds.
The 1-sigma cross-track error in the shadow position is 17.5 km.
The sky-plane scale is 3844.5 km/arcsec.
Diameter estimates:
53.7 km assuming a 5% albedo, aximum of 2.7 sec for a central chord
21.9 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 48.0 km used for deployment plan.
