The supernova impostor PSN J09132750+7627410 in NGC 2748 reached a maximum luminosity of \approx -14 mag .
It was quickly realized that its was not a true supernova , but another example of a non-terminal giant eruption .
PSN J09132750+7627410 is distinguished by multiple P Cygni absorption minima in the Balmer emission lines that correspond to outflow velocities of -400 , -1100 , and -1600 km s ^ { -1 } .
Multiple outflows have been observed in only a few other objects .
In this paper we describe the evolution of the spectrum and the P Cygni profiles for three months past maximum , the post-maximum formation of a cool , dense wind , and the identification of a possible progenitor .
One of the possible progenitors is an infrared source .
Its pre-eruption spectral energy distribution suggests a bolometric luminosity of -8.3 mag and a dust temperature of 780°K .
If it is the progenitor it is above the AGB limit unlike the intermediate luminosity red transients .
The three P Cygni profiles could be due to ejecta from the current eruption , the wind of the progenitor , or previous mass loss events .
We suggest that they were all formed as part of the same high mass loss event and are due to material ejected at different velocities or energies .
We also suggest that multiple outflows during giant eruptions may be more common than reported .
