cds-question@unistra.frexoplanetsmultiple-starsstellar-radiistellar-masseseffective-temperaturephotometryGiven that Campaign 16 of the K2 mission is one of just two K2 campaigns observed so far in "forward-facing" mode, which enables immediate follow-up observations from the ground, we present a catalog of interesting targets identified through photometry alone. Our catalog includes 30 high-quality planet candidates (showing no signs of being non-planetary in nature), 48 more ambiguous events that may be either planets or false positives, 164 eclipsing binaries, and 231 other regularly periodic variable sources. We have released light curves for all targets in C16 and have also released system parameters and transit vetting plots for all interesting candidates identified in this paper. Of particular interest is a candidate planet orbiting the bright F dwarf HD 73344 (V=6.9, K=5.6) with an orbital period of 15 days. If confirmed, this object would correspond to a 2.56+/-0.18 R_{Earth}_ planet and would likely be a favorable target for radial velocity characterization. This paper is intended as a rapid release of planet candidates, eclipsing binaries, and other interesting periodic variables to maximize the scientific yield of this campaign, and as a test run for the upcoming TESS mission, whose frequent data releases call for similarly rapid candidate identification and efficient follow up.2018AJ....156...22Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/22CatalogResearchIsServedByTAP VizieR generic servicerelated-toIV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)J/ApJ/809/25 : Stellar and planet properties for K2 candidatesJ/A+A/594/A100 : K2 new planetary and EB candidates (Barros+, 2016)J/ApJS/222/14 : Planetary candidates from 1st yr K2 missionJ/ApJS/226/7 : Planet candidates discovered using K2's 1st yrJ/AJ/155/21 : Planet candidates from K2 campaigns 5-8 (Petigura+, 2018)J/AJ/155/136 : Planets orbiting bright stars in K2 campaigns 0-10https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/22https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/22http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/22https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/22https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/22http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/22GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/AJ/156/22/table4Systems showing periodic variabilityrecnoRecord number assigned by the VizieR team.
