Notes

The averaged rate of brightness increase, accompanied by the rise of a blue continuum overwhelming the absorption bands of the M giant, and the corresponding decline in the ionization condition of the emission-line spectrum, supports the hypothesis that IPHAS J190832.31+051226.6 is a new symbiotic star detected during the onset of a (symbiotic nova?) outburst (Corradi et al., 2010). The symbiotic nature was subsequently confirmed by Corradi et al. (2010).
