Regarding this subject, infrared observations of SN 1998bu in IAUC 6907
seem to provide additional clue. The brightest reported K magnitude on
May 14 is 11.4. This value is ~0.5 mag brighter than the mean visual
magnitude on the same night. Assuming this difference is mainly due to Av
(close to the estimated Av of 0.6 mag by Yamaoka), hence K magnitude
representing "unreddened" magnitude, it looks still underluminous than
predicted by Yamaoka.
