title: Classical nova V339 Del (Nova Del 2013) - a short review
abstract: Multifrequency observations of the classical CO nova V339 Del, detected in all frequencies from $\gamma$-rays to radio, are reviewed. Nova V339 Del was discovered on 2013 August 14.584 UT. The times of decline from the brightness maximum $V$ = 4.4 mag, reached on 2013 August 16.47, UT, was estimated as $t_{2,V}$ = 10 days, $t_{3,V}$ = 18 days, so V339 Del can be classified as a fast nova with super-Eddington luminosity at maximum. The maximum-magnitude-rate-of-decline relations were used to dete
