Occultation event with (19020) 00SC6, event index number 4913
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/11/28 04:19:53 UTC
J2000 position of star is 05:27:14.7 +18:03:41
Equinox of date position of star is 05:28:49.0 +18:04:56
Star is 34 degrees from the moon. Moon is 82% illuminated.
Stellar brightness G=14.7, apparent brightess of occulting body is G=15.6
Use an exposure time of 0.60 seconds with the standard RECON-QHY system.
SNR of 9.5 per integration for unocculted signal
Expected flux drop is 70% with SNR of 6.6 for the occulted depth (per occulted point)
Apparent velocity is 17.4 km/sec on the sky relative to the star, or, 19.3 arcsec/hr.
Position angle of asteroid motion is 96.2 degrees
The recommended exposure time corresponds to 10.5 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 40.9 km.
The sky-plane scale is 3262.8 km/arcsec.
Diameter estimates:
47.0 km assuming a 5% albedo, maximum of 2.7 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.
