Regions able to see the event: Europe
Geocentric closest approach at 2026/02/08 18:14:54 UTC
J2000 position of star is 03:00:14.0 +09:24:47
Equinox of date position of star is 03:01:38.4 +09:30:55
Star is 167 degrees from the moon. Moon is 57% illuminated.
Stellar brightness G=13.8, apparent brightess of occulting body is G=16.0
Use an exposure time of 0.20 seconds with the standard RECON-QHY system.
SNR of 8.5 per integration for unocculted signal
Expected flux drop is 88% with SNR of 7.4 for the occulted depth (per occulted point)
Apparent velocity is 15.2 km/sec on the sky relative to the star, or, 15.6 arcsec/hr.
Position angle of asteroid motion is 72.8 degrees
The recommended exposure time corresponds to 3.0 km per image.
The 1-sigma error in the time of the event is 0.7 seconds.
The 1-sigma cross-track error in the shadow position is 32.8 km.
The sky-plane scale is 3521.1 km/arcsec.
Diameter estimates:
46.1 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
18.8 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 40.4 km used for deployment plan.
