Occultation event with (13182) 96SO8, event index number 3258
Regions able to see the event: Australia
Geocentric closest approach at 2026/02/17 12:59:21 UTC
J2000 position of star is 11:04:57.8 +01:34:28
Equinox of date position of star is 11:06:18.4 +01:25:59
Star is 162 degrees from the moon. Moon is 0% illuminated.
Stellar brightness G=13.1, apparent brightess of occulting body is G=16.1
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 10.4 per integration for unocculted signal
Expected flux drop is 94% with SNR of 9.8 for the occulted depth (per occulted point)
Apparent velocity is 16.9 km/sec on the sky relative to the star, or, 17.5 arcsec/hr.
Position angle of asteroid motion is 108.0 degrees
The recommended exposure time corresponds to 2.0 km per image.
The 1-sigma error in the time of the event is 1.8 seconds.
The 1-sigma cross-track error in the shadow position is 30.2 km.
The sky-plane scale is 3466.8 km/arcsec.
Diameter estimates:
41.5 km assuming a 5% albedo, maximum of 2.5 sec for a central chord
16.9 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 30.9 km used for deployment plan.
