NOVA IN THE LARGE MAGELLANIC CLOUD
Dr. J. A. Graham, Cerro Tololo Interamerican Observatory,
cables that a nova has been discovered in the Large Magellanic
Cloud, as shown below. It is approximately 14' north of HV 5946.
1970 UT R. A. (1975) Decl. Mag.
Nov. 5 5 35.8 -70 48 12-13
Dr. B. E. Westerlund, European Southern Observatory, telexes
the following photoelectric measures by Brunet:
1970 UT V B - V U - B
Nov. 7.28 12.56 +0.22 -0.65
8.31 12.80 +0.30 -0.69
He also reports that West obtained a spectrum (73 A/mm) on Nov.
8.25 UT and described it as follows: "The spectrum is typical of a
principal nova spectrum less than one magnitude after maximum. It
shows broad, violet-displaced Balmer lines H-beta - H16 in absorption and
strong emission in H-beta - H10. In H-beta - H-epsilon there are double peaks. The
Balmer jump is weak. Mg II 4481 A is barely visible. The strong,
broad K-line in absorption is violet displaced. Two narrow interstellar
K-lines are visible."
