Regions able to see the event: SAmericaN,SAmericaS
Geocentric closest approach at 2025/11/27 04:16:54 UTC
J2000 position of star is 03:34:38.3 +08:43:24
Equinox of date position of star is 03:36:02.3 +08:48:31
Star is 91 degrees from the moon. Moon is 39% illuminated.
Stellar brightness G=16.5, apparent brightess of occulting body is G=15.6
Use an exposure time of 1.00 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 32% with SNR of 1.0 for the occulted depth (per occulted point)
Apparent velocity is 17.1 km/sec on the sky relative to the star, or, 19.6 arcsec/hr.
Position angle of asteroid motion is 71.6 degrees
The recommended exposure time corresponds to 17.1 km per image.
The 1-sigma error in the time of the event is 0.6 seconds.
The 1-sigma cross-track error in the shadow position is 25.5 km.
The sky-plane scale is 3143.4 km/arcsec.
Diameter estimates:
42.7 km assuming a 5% albedo, aximum of 2.5 sec for a central chord
17.4 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 35.1 km used for deployment plan.
