Greetings,
Can anyone advise exactly where V1830 Sagittarii is and if it is still in
outburst? I've used the Downes & Shara chart from PASP but this is a little
ambiguous. Their stated limit is 14 on this chart and they identify a star
about 40" south of a star of about magnitude 10. This star is mag 14 if
their limit is accurate - the limit looks rather fainter to me.
My problem is that I have a star of mag 12 about 10" south of the tenth
magnitude star and nothing where Downes & Shara put V1830. May 16 & 17 UT.
They don't show this twelfth magnitude star. Is It V1830? Or has it now
returned to normal? I'd like to make sense of the CCD frames I have.
Regards,
Stan Walker
