Scientific paper

The Palomar Transient Factory (PTF) is a synoptic survey designed to explore the transient and variable sky. We use PTF observations of fields that were observed multiple times (≥ 10) per night, for several nights, to find asteroids, construct their lightcurves and measure their rotation periods. Here we briefly present our pipeline and preliminary results from a pilot program that covered an area of 21 deg2 for three nights with ≈ 20 min cadence. Our pipeline was able to detect 558 unique asteroids, 128 of them were unknown. We present high quality rotation periods for 64 main belt asteroids. We estimate that implementing our search for all existing high cadence PTF data will be able to establish the rotation periods for ~10,000 minor planets.
