The MAXI/GSC nova alert system triggered an X-ray increase from the transient neutron star low-mass X-ray binary Aql X-1 at 20:38 UT on 2015 February 16. The flux is about 60 mCrab in the 4-10 keV band. The Swift/BAT light curve also shows a flux increase. The last outburst of Aql X-1 started in 2014 June (ATel #6280, #6286, #6447). The MAXI/GSC light curve is updated in every 4 hours at http://maxi.riken.jp/top/index.php?cid=1&jname=J1911+005 . Multiwavelength observations of Aql X-1 are encouraged.
