Discovery paper by Bond et al. (2008).

Spitzer/IRS mid-IR spectrum taken 93 days after the maximum (Prieto et al. 2009)

• maximum absolute brightness: <math>M_V \simeq -12 to -13</math>
• detected at brightness <math>V\approx14.5 \textrm{mag}</math>
• decay to 20 mag in about 100 days
• intermediate between CN and SN
• suspected to be a twin with SN 2008S (progenitor: luminous star embedded in circumstellar dust)
