Dear all,

Today arXiv features a paper about a newly discovered quadruple quasar candidate in Andromeda called J014709+463037. The quasar seems to be at z~2.6 and the lensing system at z~0.57. The four images are 1.3" to 3.4" apart and have r magnitudes r = 15.4–17.7 mag which should put three of the four parts in reach of 20" telescopes and the fourth, and faintest, part possibly in reach of larger telescopes. The paper containing images taken with Keck can be found here

Good luck hunting this one down!


Clear skies,

Wouter
