V390 NORMAE
     D. K. Lynch, R. W. Russell, R. J. Rudy, and T. Prater, The
Aerospace Corporation; and C. E. Woodward, University of Minnesota,
report 0.8- to 5.5-micron spectroscopy of V390 Nor (cf. IAUC 8850)
using the Infrared Telescope Facility's 3-m telescope (+ SpeX) on
June 21 UT.  V390 Nor is confirmed as a classical nova well into
its emission-line phase.  While the spectrum is dominated by low-
excitation lines of H I, C I, N I, O I, and Ca II, He I features
are already evident.  Fe II emission is present but is not strong.
Weak P-Cyg profiles extending to 1800 km/s from line center are
present on the H I, He I, and O I lines and on the very strong Ca
II infrared triplet.  The reddening derived from the strong O I
lines is E(B-V) approximately 1.0, and there is no evidence of dust
in the nova shell.

     Six additional apparent supernovae have been found on
unfiltered CCD frames and given designations:  2007cl by T. Puckett
and G. Sostero (cf. IAUC 8843); 2007cm by W. Kloehr (cf. IAUC 8789);

Telegrams:  2007cl in NGC 6479, CBETs 972, 974 (type-Ic, discovered
a few days past maximum); 2007cm in NGC 4644, CBETs 973, 974 (young,
type-IIn supernova); 2007cn in UGC 11953, CBET 975; 2007co in MCG
+05-43-16, CBETs 977, 978 (type-Ia, discovered well before maximum);
2007cp in IC 807, CBETs 980, 981 (type-Ia); 2007cq, CBET 983.  Note
that 2007ck (cf. IAUC 8843) was discovered in MCG +05-43-16 only a
couple of weeks before 2007co was found.
