[Taichi Kato <tkato>]

V893 Sco outburst

    The (grazing) eclipsing dwarf nova below the period gap is in outburst,
as indicated by the following observations.  The present outburst is the
first one in this season, and is one of relatively bright ones recorded
recently.  (Southern) observers are strongly urged to obtain time-resolved
photometry of this object.  The object had long been lost, and was
recovered by K. Haseda (vsnet-alert 1543, 1545, 1565, 1637, 1647; summarized
in IBVS 4585).  The spectroscopic confirmation (vsnet-alert 1688), which
finally led to the discovery of the eclipsing nature (vsnet-alert 3432).
