LILLER'S VARIABLE IN NORMA (NOVA NORMAE 1985)
R. H. McNaught, Siding Spring Observatory, reports the
following magnitude estimates (B and V with respect to a nearby
photoelectric sequence) from his examination of old charts: 1916 July
5, B [ 15.5 (Union Observatory); 1960 Aug. 26, mag 16 (at limit of
Southern Milky Way chart, 103a-D emulsion); 1966 Apr. 21, B = 15.4
(Canterbury); 1970 Apr. 11, B [ 16.5 (Atlas Stellarum); 1973 July
1, V [ 12.6 (Papadopoulos); 1975 July 12, B = 16.9 (ESO B); 1976
May 5, J = 14.8 (UKSTU J); 1982 Apr. 19, bright (UKSTU I). He
also provides recent visual magnitudes: 1985 Jan. 31.75 UT, 12.7;
Feb. 1.76, 12.7; 2.75, 12.7; 3.77, 12.7; 5.78, 13.3:. It appears
that the object is a red long-period variable.

Yudin and N. Yu. Yutanov, Main Astronomical Observatory of the
U.S.S.R. Academy of Sciences; and K. S. Kuratov and D. B. Mukanov,
Astrophysical Institute of the Kazakh S.S.R. Academy of Sciences,
report the following photoelectric observations, obtained with the
1.0-m Kazakh telescope. Standard deviations are + 0.02 mag in U,
B, V and R, + 0.05 mag in I, J and H, and + 0.09 mag in K.

1E 1402.3+0416
P. Giommi and P. Barr, EXOSAT Observatory, report that EXOSAT
observations of the BL-Lac object 1E 1402.3+0416 on Feb. 1 yield a
mean 0.3-3.5-keV intensity of 1.4 x 10**-14 J m**-2 s**-1, a factor of
ten higher than that previously found by the Einstein Observatory.
In addition, variability by a factor of two on a timescale of less
than 6 hr was detected. Optical and radio observations are urged.
