Filtered Photometric Monitoring of 1591 Baize
Pages 311-312
Bentz, Misty C.; Abbot, Caleb; Agudelo, Steven; Dassing, Steven; Flynn, Wyatt; Gibbs, Austin; Gonzalez, Louis; Kim, Bokyoung; Paredes, Leonardo; Toben, Christopher; Vrijmoet, Eliot Halley; Yep, Alexandra

Broad-band BVR photometry of asteroid 1591 Baize was obtained over four nights in 2017 February and March. We determined a rotation period of 7.788 ± 0.003 hours and typical colors of B-V = 0.9 and V-R = 0.5. The amplitude of color variations is small, ~0.02 mag. These characteristics support the classification of 1591 Baize as an S-type asteroid.

Lightcurve Photometry Opportunities: 2018 October-December
Pages 404-408
Warner, Brian D.; Harris, Alan W.; Durech, Josef; Benner, Lance A.M.

We present lists of asteroid photometry opportunities for objects reaching a favorable apparition and have no or poorly-defined lightcurve parameters. Additional data on these objects will help with shape and spin axis modeling via lightcurve inversion. We also include lists of objects that will or might be radar targets. Lightcurves for these objects can help constrain pole solutions and/or remove rotation period ambiguities that might not come from using radar data alone.
