NOVA
Dr. H. Hirose, Tokyo Astronomical Observatory, cables that
Honda has discovered a nova, as shown below. The position appears
to be in Serpens Cauda, near the border with Ophiuchus.
1970 UT R.A. (1950) Decl. mv
Feb. 13.860 18 28.2 + 2 40 7.0
A further observation by Honda on Feb. 15.842 UT shows that the
nova had brightened to visual magnitude 5.0.

the angle between them 37.3o.
