It first erupted in 1919, reaching magnitude 7. Its other eruptions in 1901, 1973 and 1991 only reached magnitude 10, leading it to be reclassified from a recurrent nova to a dwarf nova.[2] References1. ^1 {{cite web |title=V1017 Sagitarii |publisher=SIMBAD Astronomical Database |url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=V1017+Sagittarii |accessdate=26 April 2015}} {{Stars of Sagittarius}}{{Novae}}{{multi-star-stub}}{{var-star-stub}}2. ^{{cite journal|last=Schaefer|first=Bradley E.|date=2010|title=Comprehensive Photometric Histories of All Known Galactic Recurrent Novae|journal=The Astrophysical Journal Supplement|volume=187|issue=2|pages=275–373|doi=10.1088/0067-0049/187/2/275 |bibcode=2010ApJS..187..275S|arxiv = 0912.4426 }} 7 : Dwarf novae|Sagittarius (constellation)|Objects with variable star designations|2MASS objects|G-type giants|White dwarfs|Eclipsing binaries |
