Pravec (2006) Lightcurve plot of (15415) Rika by Husárik and Kusnirák, from Ondrejov data published by the NEO Photometric Program and collaborating projects: rotation period 6.3632±0.0007 hours (basically identical with 6.3636±0.0008 h) and a brightness amplitude of 1.06 mag. Quality code is 3. Summary figures at the LCDB.
