POSSIBLE NOVA IN SGR
Waagen and Green telex that Albrecht has reported a possible nova
in Sgr at:
RA 18h04.5m DEC -22 05'(1950)
On Sept 3 it was recorded at mag 10, fading to 11.7 on Sept 14.
An appeal for spectral confirmation has been issued.
Does anyone have photos of this area taken in recent months?

Q1989/67
Further to the note on E342, further research shows this to be:
SAOC 076192 RA 03h44m22s DEC +23 57'47"(1950)
The SAOC has mv=8.1 but other sources agree on V=6.3 although this
differs from John's result of 7.3 on Sept 4. Possibly the
presence of the mag 3.0 nearby makes estimates difficult. The
object is missing from specialised charts which 'mask' the spot by
the large size used to plot the brighter mag 3 star.

NSV 01098
Further to the note on E341, Mike Collins has now drawn a 'C' chart
from photographs by D.Buczynski of 1989 Jan 13. The sequence has
been extended to 13.6 to cover the full amplitude and copies are
available from the Editor on e-mail request.
