M. M. Kasliwal, R. Quimby, and S. R. Kulkarni, California Institute of Technology, report that spectroscopy (range 360-900 nm) of M31N 2008-11b (cf. CBET 1588) obtained on Dec. 4.22 UT with the Double Beam Spectrograph on the Palomar Hale 5-m telescope reveals a steep blue continuum, very narrow emission in H-alpha, and broad absorption in H-beta through at least H-eta. Further, there is a faint blue counterpart in Sloan Digital Sky Survey "DR Supplement" g-band imaging, with magnitudes g = 22.8 and r > 23.3 (nothing visible in r, to 3 sigma) on 2002 Oct. 6. Given the reported peak magnitude of 14.5 (CBET 1588), this outburst had an amplitude of > 8 mag. Kasliwal et al. suggest that this optical transient is an SU-UMa-like superoutburst in our own galaxy, similar to HS 2219+1824 (Rodriguez-Gil et al. 2005, A.Ap. 440, 701).
