Abstract
The near-Earth asteroid 2015 CN13 made a fly-by of Earth in late 2015 February. We observed the asteroid on Feb 25, 26, and 28. Analysis of the data set found two possible periods, the most likely being P = 22.7 ± 0.3 h. Given the estimated diameter of 70 meters and long period, this puts 2015 CN13 in a small group of NEAs with D ≤ 140 meters and periods well below the spin barrier, i.e., approximately P ≥ 2.2 hours.
