Occultation event with (19020) 00SC6, event index number 4982
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/12/02 00:09:59 UTC
J2000 position of star is 05:25:09.1 +18:06:56
Equinox of date position of star is 05:26:43.5 +18:08:16
Star is 87 degrees from the moon. Moon is 42% illuminated.
Stellar brightness G=16.2, apparent brightess of occulting body is G=15.5
Use an exposure time of 0.75 seconds with the standard RECON-QHY system.
SNR of 3.0 per integration for unocculted signal
Expected flux drop is 34% with SNR of 1.0 for the occulted depth (per occulted point)
Apparent velocity is 18.0 km/sec on the sky relative to the star, or, 19.9 arcsec/hr.
Position angle of asteroid motion is 96.3 degrees
The recommended exposure time corresponds to 13.5 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 40.7 km.
The sky-plane scale is 3254.0 km/arcsec.
Diameter estimates:
47.0 km assuming a 5% albedo, maximum of 2.6 sec for a central chord
19.2 km assuming a 30% albedo, maximum of 1.1 sec for a central chord
Cross-track diameter of 42.6 km used for deployment plan.
