Query: KMT-2018-BLG-1990Lb: A Nearby Jovian Planet From A Low-Cadence
  Microlensing Field   We report the discovery and characterization of KMT-2018-BLG-1990Lb, a Jovian
planet $(m_p=0.57_{-0.25}^{+0.79}\,M_J)$ orbiting a late M dwarf
$(M=0.14_{-0.06}^{+0.20}\,M_\odot)$, at a distance
$(D_L=1.23_{-0.43}^{+1.06}\,\kpc)$, and projected at $2.6\pm 0.6$ times the
snow line distance, i.e., $a_{\rm snow}\equiv 2.7\,\au (M/M_\odot)$, This is
the second Jovian planet discovered by KMTNet in its low cadence ($0.4\,{\rm
hr}^{-1}$) fields, demonstrating that this population will be well
characterized based on survey-only microlensing data.
