Dear colleagues,
Regarding the comments on V1830 Sgr, that appeared on this vsnet-chat, I'd like
to add following information.
V1830 Sgr has been reported several times in outburst since 1991. The list
below is an extract of the Outburst Activity Database on Selected Cataclysmic
Variables.
V1830 SGR
UG 11.5p 17.5p
Outburst date JD Max mag Observer Reference
1991.0708 48446 12.0 Overbeek AAVSO Circ. 250
1992.0314 48696 11.8 Overbeek AAVSO Circ. 258
1993.0220 49039 12.0 Overbeek AAVSO Circ. 269
1993.0707 49176 12.0 Williams, Overbeek [TAEC 758] [AAVSO Circ. 274]
1994.0529 49502 12.0 Overbeek AAVSO Circ. 284
1994.0915 49611 12.0 Overbeek AAVSO Circ. 288
1995.1021 50012 12.2 Stewart, Overbeek AAVSO Circ. 301
1996.0710 50275 12.2 Overbeek AAVSO Circ. 310
Note that V1830 Sgr has been as bright on each of these occasions as it is
during
the current outburst.
Dannie Overbeek might be able to comment more precisely on the outburst
behaviour
of this dwarf nova. He's probably the one who observed it most frequently.
Regards,
Tonny Vanmunster
