  The POSS I digitized image (thanks to USNO Flagstaff) taken on
1958.5257 with 103aO (Bj) shows this object much brighter than in
other Bj images, such as POSS I Bj taken on 1958.2957.  Thus this
object has also a large amplitude in photographic band, which is
consistent with the description of V4006 Sgr, and the reports by
Haseda-san and others.
