NOVA MUSCAE 1983
     E. Budding, Carter Observatory, Wellington, provides the
following averaged photometric observations, obtained at the Black
Birch Observatory: Jan. 22.616 (heliocentric) UT, V = 8.71, B-V =
+0.19, U-B = -0.82; 30.538, 9.22, +0.11, -0.71; 31.519, 9.11,
+0.17, -0.75; Feb. 2.532, 9.17, +0.15, -0.66; 5.573, 9.40, +0.55,
-0.97.  The brightness was essentially constant over 0.08 day on
Jan. 22, but minor fluctuations were noted within minutes on Feb.
5.  Comparison stars were HD 102249, 102584 and 103402.


VARIABLE STAR IN ARA
     W. Liller, Vina del Mar, Chile, writes that spectrograms of
this object (IAUC 3840, 3844, 3847) obtained by J. Jugaku at Cerro
Tololo in late July show the strong series of TiO bands
characteristic of a very cool, long-period variable.
