About this image

Latest spectrum of the nova shows a dramatic change since my spectra on 28th August and 7th September. Very strong P-Cygni profiles have now developed. Most clearly seen from H beta and shorter wavelengths (higher dispersion in the blue with the prism).

The AAVSO light-curve (see AAVSO light curve generator) shows that the magnitude is rising again...can anyone explain what is happening???

Field of view 55 x 34 arc minutes with north and red up.
