Photometry of asteroids (5141), (43032), (85953), (259221), and (363599) observed at Pic du Midi Observatory

TL;DR

This paper presents optical observations and light curves of several asteroids at Pic du Midi Observatory, linking their physical properties to associated meteoroid streams and providing new data on their colors and reflectances.

Contribution

First observational data of asteroid physical properties related to meteoroid streams, including light curves and colors, expanding knowledge of asteroid-meteoroid stream connections.

Findings

Light curve of asteroid (259221) 2003 BA21 presented

Colors and reflectances of asteroid (363599) 2004 FG11 provided

Colors of asteroids (5141) Tachibana and (43032) 1999 VR26 reported

Abstract

These are the first results of an observational program devoted to the complete physical data of asteroids that could produce or feed meteoroid streams. Our results are based on the optical observation at Pic du Midi observatory in April 6-7, 2016 and January 17-18, 2018. We will present the light curve of asteroid (259221) 2003 BA21, associated with Daytime Sextantids (221 DSX) and November theta Aurigids (390 THA); the light curves and colors of asteroid (363599) 2004 FG11, associated with Daytime zeta Perseids (172 ZPE) as well as g-r and g-i; and the corresponding reflectances for the (85953) 1999 FK21, associated with Daytime eta Sagittariids (100 XSA). We will also present the colors for two additional objects, namely, (5141) Tachibana and (43032) 1999 VR26.
