NOVA VULPECULAE, 1968

On April 15, Mr. G.E.D. Alcock of Peterborough, England, discovered his second nova
within a year. At that tine, the magnitude was 5.6. By April 17, it had bright-
ened to about magnitude 4.5. The following precise position of this nova was
reported on I.A.U. card no. 2067:

             R.A. 19:45:57.41;   Dec. 27° 02' 48."4N.     Epoch 1950

This naked-eye nova is well placed during the morning hours. A chart showing the area
within a few degrees of the nova may be prepared from the following list of stars.
This is a selection of stars from the SAO Catalog of 258,997 stars, and is complete
within about one degree of the nova. Brighter stars are listed out to about three
degrees. Magnitudes are approximate, and some may be variable stars, so that several
stars should be used when making magnitude estimates.
