Occultation event with (6997) Laomedon, event index number 4488
Regions able to see the event: SAfrica
Geocentric closest approach at 2026/10/26 00:55:06 UTC
J2000 position of star is 04:59:41.4 +04:57:21
Equinox of date position of star is 05:01:06.9 +04:59:40
Star is 48 degrees from the moon. Moon is 100% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.65 seconds with the standard RECON-QHY system.
SNR of 3.1 per integration for unocculted signal
Expected flux drop is 51% with SNR of 1.6 for the occulted depth (per occulted point)
Apparent velocity is 13.6 km/sec on the sky relative to the star, or, 13.6 arcsec/hr.
Position angle of asteroid motion is 48.0 degrees
The recommended exposure time corresponds to 8.8 km per image.
The 1-sigma error in the time of the event is 1.6 seconds.
The 1-sigma cross-track error in the shadow position is 27.1 km.
The sky-plane scale is 3589.9 km/arcsec.
Diameter estimates:
45.5 km assuming a 5% albedo, maximum of 3.4 sec for a central chord
18.6 km assuming a 30% albedo, maximum of 1.4 sec for a central chord
Cross-track diameter of 37.5 km used for deployment plan.
