Occultation event with (15033) 98VY29, event index number 3408
Regions able to see the event: Australia
Geocentric closest approach at 2026/03/12 10:32:06 UTC
J2000 position of star is 12:56:30.2 -19:45:57
Equinox of date position of star is 12:57:53.9 -19:54:26
Star is 72 degrees from the moon. Moon is 40% illuminated.
Stellar brightness G=10.3, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.12 seconds with the standard RECON-QHY system.
SNR of 51.0 per integration for unocculted signal
Expected flux drop is 100% with SNR of 50.8 for the occulted depth (per occulted point)
Apparent velocity is 14.8 km/sec on the sky relative to the star, or, 15.0 arcsec/hr.
Position angle of asteroid motion is 105.9 degrees
The recommended exposure time corresponds to 1.8 km per image.
The 1-sigma error in the time of the event is 1.5 seconds.
The 1-sigma cross-track error in the shadow position is 33.6 km.
The sky-plane scale is 3532.0 km/arcsec.
Diameter estimates:
43.8 km assuming a 5% albedo, maximum of 3.0 sec for a central chord
17.9 km assuming a 30% albedo, maximum of 1.2 sec for a central chord
Cross-track diameter of 33.3 km used for deployment plan.
