Another Quadruply Lensed Quasar from the VST-ATLAS Survey
  We report the quadruple nature of the source WISE 025942.9-163543 as observed
in the VST-ATLAS survey. Spectra of the two brightest images show quasar
emission lines at z=2.16. The system was discovered by splitting ATLAS
"cutouts" of WISE sources with W1-W2 > 0.7, when possible, into three
components. Followup Magellan images were used to obtain astrometry and g and i
photometry, with i=18.78 and 19.73, respectively, for the brightest and
faintest components. Absorption lines are observed at z=0.905 but there is
little evidence for a lensing galaxy after PSF fitting and subtraction. Saha
and Williams (2003) would classify ATLAS 0259-1635 as a short-axis quad. The
larger and smaller diameters are 1.57 and 1.32 arcseconds, respectively.
Modeling the lensing galaxy as a singular isothermal sphere with external
shear, the largest and smallest predicted magnifications are 10.8 and 6.4
respectively.
