yes !

outburst probably started in the end of october if we look closer to the BESS datatabase,

it has nicely evolved in the last days, in intensity but also in the V/R asymetry of Ha lines which has reversed in the begining of november (Spectra taken with a StarEX2400, 35 µm slit; H2O lines removed)
