Occultation event with (15033) 98VY29, event index number 3391
Regions able to see the event: Australia
Geocentric closest approach at 2026/03/10 15:05:11 UTC
J2000 position of star is 12:57:14.1 -19:48:49
Equinox of date position of star is 12:58:37.8 -19:57:17
Star is 51 degrees from the moon. Moon is 57% illuminated.
Stellar brightness G=15.7, apparent brightess of occulting body is G=16.2
Use an exposure time of 0.55 seconds with the standard RECON-QHY system.
SNR of 4.2 per integration for unocculted signal
Expected flux drop is 62% with SNR of 2.6 for the occulted depth (per occulted point)
Apparent velocity is 14.3 km/sec on the sky relative to the star, or, 14.5 arcsec/hr.
Position angle of asteroid motion is 104.9 degrees
The recommended exposure time corresponds to 7.9 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 34.3 km.
The sky-plane scale is 3541.2 km/arcsec.
Diameter estimates:
43.8 km assuming a 5% albedo, maximum of 3.1 sec for a central chord
17.9 km assuming a 30% albedo, maximum of 1.3 sec for a central chord
Cross-track diameter of 33.3 km used for deployment plan.
