The BOOTES-1A wide field image telescope at the BOOTES-1 station in Mazagon (INTA-CEDEA, Huelva, Spain) telescope automatically detected a rise in the flux of the ASASSN-14FC dwarf-nova at 00:09:11 UT on 7 May 2022. Its optical flux increased to 15.1 mag. (i.e. an increase of 2 mag.) in clear filter using Gmag from gaia on photometry calibration. ~3 days before the outburst detection (2022-05-03 23:28:20) we do not detect any source at given coordinates with a limit magnitude of 14.7. Following this alert, a set of three images were obtained 2-3 days after with the BOOTES-1B 0.3m robotic telescope located nearby.
