Hiroyuki Naito, Nayoro Observatory, and Tatsuharu Ono, Hokkaido University, report that a low-dispersion spectrum (R about 300 at 650 nm) of this object was obtained on Apr. 29.58 UT using the 1.6-m Pirka telescope (+ NaCS) at the Nayoro Observatory. The spectrum shows some unidentified absorption lines on a very red continuum, which may indicate high reddening.
