V1302 AQUILAE (IRC +10420)
     C. E. Irvine, Monterey Institute for Research in Astronomy,
communicates:  "Reticon spectra of IRC +10420 (V1302 Aql) taken
between 1986 July 3 and Nov. 3 on the 0.9-m telescope show strong
new emission features:  H-alpha; Ca II triplet (849.8, 854.2, 866.3 nm);
and [Ca II] (729.1 and 732.3 nm).  Coude spectra taken by G. H.
Herbig on the 3-m Shane reflector at Lick Observatory on 1972 Nov.
18 show only weak emission wings at H-alpha and no Ca II triplet
emission. Humphreys et al. (1973, Ap.J. 179, L49) did not report any
emission in their blue and near-infrared spectra, from which it was
classified as an F8 supergiant.  Fix (1981, Ap.J. 248, 542) did not
report any emission in his 500-800-nm spectra obtained in 1980.
CCD spectra obtained by Herbig on 1986 Dec. 9 and 10 on the 3-m
Lick telescope, with a resolution of 0.05 nm, show H-alpha and the Ca II
triplet to have central reversals.  The [Ca II] lines do not show
reversals.  These and the MIRA spectra show emission features for
which the preliminary indentifications include Fe II, [Fe II], [Ni
II], and [O II]."


NOVA ANDROMEDAE 1986
     D. L. King, Royal Greenwich Observatory, provides an accurate
position that is identical to that on IAUC 4282 except in seconds
of R.A. (47s.60); he further notes that there is a star of mpg about 17.8
in this position on the Palomar Sky Survey blue exposure.
     C. C. Huang, Purple Mountain Observatory, reports that spectroscopic
observations on Dec. 10 revealed very wide, strong H-beta, H-gamma,
H-delta, and H-epsilon emission and sharp interstellar H and K lines.
     Further visual magnitude estimates (cf. IAUC 4282), provided
in part by J. Mattei, AAVSO:  Dec. 10.14 UT, 7.0 (A. Hale, Las
Cruces, NM); Dec. 10.517, 7.1 (Y. Sugiyama, Hiratsuka, Japan);
12.11, 7.3 (C. Stephan, Sebring, FL); 13.12, 7.8 (P. Collins,
Tucson, AZ); 14.16, 7.9 (D. Megginson, St. Charles, MO); 15.04,
7.3 (Stephan).


SUPERNOVA 1986L IN NGC 1559
     Further visual magnitude estimates (cf. IAUC 4270) by R. H.
McNaught, reported via J. A. Mattei, AAVSO:  Nov. 1.58 UT, 13.8;
4.48, 14.0; 5.44, 14.5; 8.71, 14.3; 9.69, 14.3; 21.50, 14.3; 24.48,
14.4; 28.60, 14.8; Dec. 2.60, 14.9; 4.57, 14.8; 11.73, 15.3.
