Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/08/21 06:04:44 UTC
J2000 position of star is 04:28:50.8 +13:57:02
Equinox of date position of star is 04:30:20.9 +14:00:27
Star is 167 degrees from the moon. Moon is 61% illuminated.
Stellar brightness G=11.7, apparent brightess of occulting body is G=15.8
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 25.1 per integration for unocculted signal
Expected flux drop is 98% with SNR of 24.5 for the occulted depth (per occulted point)
Apparent velocity is 17.4 km/sec on the sky relative to the star, or, 16.1 arcsec/hr.
Position angle of asteroid motion is 91.2 degrees
The recommended exposure time corresponds to 2.1 km per image.
The 1-sigma error in the time of the event is 0.3 seconds.
The 1-sigma cross-track error in the shadow position is 24.3 km.
The sky-plane scale is 3895.8 km/arcsec.
Diameter estimates:
60.5 km assuming a 5% albedo, maximum of 3.5 sec for a central chord
24.7 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 47.7 km used for deployment plan.
