NOVA AQUILAE 1970
     Dr. Y. Kozai, Tokyo Astronomical Observatory, reports the
following preliminary photoelectric results, obtained with a 91-cm
reflector at the Okayama station:

     1970 UT       V    B - V  U - B  Observer       Notes
     Apr. 15.80   7.4   +0.6   -0.1   H. Ohtani      through clouds
          21.76   7.44  +0.49  -0.37  K. Ichimira
          26.82   8.28                S. Nishiuura   through clouds
          28.82   8.41  +0.47  -0.56    "
          29.81   8.49  +0.41  -0.60    "

On April 15.79 UT T. Tsuji obtained a coude spectrogram of the blue
and violet regions with the 188-cm reflector at Okayama (f/4, 10 A/
mm).  The spectrum had the appearance of that of an A or F type
star.  The radial velocity from the absorption lines was about -600
km/s.  Emission lines were not yet strong.  At the Dodaira station,
prism spectrograms of the visual and photographic regions (60 A/mm
at H-gamma) were obtained on April 15.74 by K. Tonita and on April 16.79
by S. Kikuchi.  These two spectrograms were underexposed.  Emission
of H-alpha was strong, and H-beta, H-gamma, H-delta and some other faint
emissions were visible.
