We report the MAXI/GSC detection of a new X-ray outburst of the transient low mass X-ray binary 4U 1711-34. MAXI/GSC data show that the 4-10 keV X-ray flux has increased since 2016 November 18 (MJD 57710), and reached a maximum of 0.061+/-0.008 photons/s/cm2 (~ 53 mCrab) on November 20. (Note that the 2-4 keV light curve of MAXI data products shows regular false increases due to severe soft X-ray leaks from GX 349+2.) The source flux has been below the detection limit of MAXI/GSC since November 25, and currently can not be observed because the source is close to the sun.

This is the second outburst detected by MAXI for 7 years, and the previous outburst was on 2010 February (ATel #2425).
