GK Persei (also Nova Persei 1901) was a bright nova occuring in 1901 in Perseus. It reached a maximum magnitude of 0.2, the brightest nova of modern times until Nova Aquilae 1918. This article needs to be cleaned up to conform to a higher standard of quality. ... 1901 was a common year starting on Tuesday (see link for calendar). ... Perseus is a northern constellation, named after the Greek hero who slew the monster Medusa. ... The apparent magnitude (m) of a star, planet or other heavenly body is a measure of its apparent brightness; that is, the amount of light received from the object. ... V603 Aquilae (or Nova Aquilae 1918) was a bright nova occuring in Aquila in 1918. ...
It was discovered by Thomas David Anderson. Thomas David Anderson (February 6, 1853 – March 31, 1932) was a Scottish amateur astronomer. ...
Right ascension (RA; symbol α: Greek letter alpha) is the astronomical term for one of the two coordinates of a point on the celestial sphere when using the equatorial coordinate system. ... In astronomy declination (dec) is one of the two coordinates of the equatorial coordinate system, the other being either right ascension or hour angle. ...
The stars alpha Persei, gamma Persei, tau Persei, and iota Persei form Perseus' head: gamma Persei is of the third magnitude.
The stars alpha Persei, psi Persei, delta Persei, 48 Persei, mu Persei, and lambda Persei form Perseus' left arm and hand: delta Persei being of the third magnitude.
Stars epsilon Persei, xi Persei, zeta Persei, and omicron Persei form Perseus' left leg and foot: zeta Persei being of the third magnitude.
The unusual nova shell GK Per is the result of NovaPersei1901, a nova which exploded in 1901 about 1500 light years away in the direction of the constellation Perseus.
The first bright nova of the 20th century and the first to be subjected to detailed spectroscopy and photometry, NovaPersei1901 reached a maximum brightness of 0.2m and declined very rapidly thereafter to its current minimum of 13.1.
GK Per is unique among classical novae, having the longest known period (almost two days) and showing dwarf nova-like outbursts of about 3 mag.
