[en] V1668 Cygni

V1668 Cygni was a nova that appeared in the northern constellation of Cygnus, situated a couple of degrees to the southeast of the star Rho Cygni.[7] It was discovered by Canadian variable star observer Warren Morrison on September 10, 1978,[8] and reached a peak brightness of around 6.22 apparent magnitude on September 12.[2] The luminosity of the source at this time was about 100,000 times the brightness of the Sun, and likely remained at that level for several months. The expansion velocity of the nova shell was deduced through spectroscopy to be 1,300 km/s.[9]
