Occultation event with (19020) 00SC6, event index number 5067
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/06 08:07:43 UTC
J2000 position of star is 05:22:42.4 +18:10:50
Equinox of date position of star is 05:24:16.9 +18:12:15
Star is 142 degrees from the moon. Moon is 7% illuminated.
Stellar brightness G=12.8, apparent brightess of occulting body is G=15.5
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 12.6 per integration for unocculted signal
Expected flux drop is 92% with SNR of 11.6 for the occulted depth (per occulted point)
Apparent velocity is 18.5 km/sec on the sky relative to the star, or, 20.5 arcsec/hr.
Position angle of asteroid motion is 96.5 degrees
The recommended exposure time corresponds to 2.2 km per image.
The 1-sigma error in the time of the event is 0.6 seconds.
The 1-sigma cross-track error in the shadow position is 41.0 km.
The sky-plane scale is 3248.0 km/arcsec.
Diameter estimates:
47.0 km assuming a 5% albedo, maximum of 2.5 sec for a central chord
19.2 km assuming a 30% albedo, maximum of 1.0 sec for a central chord
Cross-track diameter of 42.6 km used for deployment plan.
