We present a deep imaging and spectroscopic search for emission from (3200) Phaethon, a large near-Earth asteroid that appears to be the parent of the strong Geminid meteoroid stream, using the 4.3 m Lowell Discovery Telescope. Observations were conducted on 2017 December 14-18 when Phaethon passed only 0.07 au from the Earth. We determine the $3\sigma$ upper level of dust and CN production rates to be 0.007-0.2 $\mathrm{kg~s^{-1}}$ and $2.3\times10^{22}~\mathrm{molecule~s^{-1}}$ through… Expand
