GK Persei
From Wikipedia, the free encyclopedia
GK Persei (also Nova Persei 1901) was a bright nova occurring in 1901 in Perseus, with right ascension 03h 31m 12s and declination +43° 54′ 17″. It reached a maximum magnitude of 0.2, the brightest nova of modern times until Nova Aquilae 1918. Unlike Nova Aquilae 1918, after fading into obscurity at about magnitude 12 to 13 during the early 20th century, GK Persei began displaying infrequent outbursts of 2 to 3 magnitudes (about 7 to 15 times quiescent brightness). Since about 1980, these outbursts have become quite regular, typically lasting about two months and occurring about every three years. Thus, GK Persei has seemed to change from a classical nova like Nova Aquilae 1918, to more recently resemble a typical dwarf nova-type cataclysmic variable star.
Nova Persei 1901 was discovered by Thomas David Anderson.

This nova figures in the plot of H. P. Lovecraft's short story "Beyond the Wall of Sleep".
