V4744 Sgr: deep fading!
Seiichiro Kiyota (Tsukuba, Japan) reports that V4744 Sgr (the fourth nova
in Sgr last year) has experienced a dramatic fading. The nova has been
proposed to be an Fe II-class nova caught during the early stage of an
outburst (cf. vsnet-alert 7566, 7576). Together with the slow fading and
the narrowness of the emission lines observed in November (before the solar
conjunction), the nova may have experienced a dust fading as observed
in the slow nova V705 Cas. (We should also bear in mind that V4744 Sgr
was once reported to show some spectroscopic similarities with V838 Mon,
cf. vsnet-alert 7566).
