Occultation event with (19020) 00SC6, event index number 4153
Regions able to see the event: SAmericaN
Geocentric closest approach at 2026/09/02 06:27:14 UTC
J2000 position of star is 05:32:21.6 +17:19:56
Equinox of date position of star is 05:33:54.7 +17:20:58
Star is 42 degrees from the moon. Moon is 73% illuminated.
Stellar brightness G=15.2, apparent brightess of occulting body is G=16.4
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 6.2 per integration for unocculted signal
Expected flux drop is 75% with SNR of 4.6 for the occulted depth (per occulted point)
Apparent velocity is 18.3 km/sec on the sky relative to the star, or, 16.4 arcsec/hr.
Position angle of asteroid motion is 85.0 degrees
The recommended exposure time corresponds to 10.0 km per image.
The 1-sigma error in the time of the event is 1.0 seconds.
The 1-sigma cross-track error in the shadow position is 37.7 km.
The sky-plane scale is 4013.3 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.
