We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates (Rpl<2.0R⊕) and 19 gaseous candidates (Rpl>2.0R⊕). Within this list we find one multi-planet system (EPIC 246042088). These two sub-Neptune (2.99±0.02R⊕ and 3.44±0.02R⊕) planets exist in a near 3:2 orbital resonance. The discovery of this multi-planet system is important in its addition to the list of known multi-planet systems within the K2 catalog, and more broadly in understanding the multiplicity distribution of the exoplanet population (Zink et al. 2019). The candidates on this list are anticipated to generate RV amplitudes of 0.2-18 m/s, many within the range accessible to current facilities.
