Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/04/08 03:57:09 UTC
J2000 position of star is 12:06:05.1 -16:59:30
Equinox of date position of star is 12:07:26.2 -17:08:17
Star is 77 degrees from the moon. Moon is 69% illuminated.
Stellar brightness G=14.3, apparent brightess of occulting body is G=13.2
Use an exposure time of 0.70 seconds with the standard RECON-QHY system.
SNR of 9.9 per integration for unocculted signal
Expected flux drop is 27% with SNR of 2.6 for the occulted depth (per occulted point)
Apparent velocity is 15.9 km/sec on the sky relative to the star, or, 19.4 arcsec/hr.
Position angle of asteroid motion is 116.8 degrees
The recommended exposure time corresponds to 11.2 km per image.
The 1-sigma error in the time of the event is 2.4 seconds.
The 1-sigma cross-track error in the shadow position is 28.0 km.
The sky-plane scale is 2960.6 km/arcsec.
Diameter estimates:
118.0 km assuming a 5% albedo, maximum of 7.4 sec for a central chord
48.2 km assuming a 30% albedo, maximum of 3.0 sec for a central chord
Cross-track diameter of 111.7 km used for deployment plan.
