J. M. Silverman, D. Wong, A. V. Filippenko, and R. Chornock, University of California, Berkeley, report that inspection of CCD spectra (range 330-1050 nm), obtained on Dec. 1 UT with the Shane 3-m telescope (+ Kast) at Lick Observatory, shows that both 2006qq and 2006qr are type-II supernovae: "SN 2006qq exhibits strong, very narrow (FWHM about 900 km/s) H-alpha emission on a relatively featureless continuum, and the other members of the hydrogen Balmer series are weak or absent (though the spectrum is noisy there). SN 2006qq thus resembles the type-IIn supernova 2002kg (cf. IAUC 8051) and its brethren. We have previously argued that they may be superoutbursts of luminous variable stars (e.g., Filippenko et al. 1995, A.J. 110, 2261; Van Dyk et al. 2000, PASP 112, 1532). However, SN 2006qq is quite luminous (absolute magnitude M_V = -18.4 if H_o = 73 km/s/Mpc; the recession velocity of the host galaxy is 8708 km/s, according to NED), unlike most such superoutbursts, so it might indeed be a genuine supernova. The H-alpha profile of 2006qr is dominated by broad (FWHM about 12000 km/s) emission; the absorption component is weak."
