Abstract
FOLLOWING notification by P. C. Gregory of the discovery of the radio outburst in Cygnus, we attempted to detect a visible object at the radio position over 6 nights, at several wavelengths from the blue to the near infrared. Direct photographs were taken with the Palomar 48-inch Schmidt camera and measurements were made at the prime focus of the 200-inch telescope with a new integrating two-dimensional silicon vidicon photometer1. The relevant data are given in Table 1.
