This pair is part of the Halton Arp catalog as Arp 259 and the Hickson Compact Group as HCG 31A (NGC 1741A) and HCG 31B (NGC 1741B).[6][5] References1. ^{{cite web|title=NGC 1741|url=http://simbad.u-strasbg.fr/simbad/sim-basic?Ident=NGC+1741|website=simbad.u-strasbg.fr|accessdate=25 February 2017}} {{Sky|05|01|38.3|-|04|15|25.2|184000000}}{{Astronomical catalogs|NGC=1741|Arp=259}}{{galaxy-stub}}2. ^{{cite web|title=NASA/IPAC Extragalactic Database|url=http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC+1741|website=nedwww.ipac.caltech.edu|accessdate=25 February 2017}} 3. ^{{cite web|title=Revised NGC Data for NGC 1741|url=http://spider.seds.org/ngc/revngcic.cgi?NGC1741|website=spider.seds.org|accessdate=25 February 2017}} 4. ^1 {{cite web|title=Hubble Reveals Young Starburst Activity in Colliding Galaxies|url=https://www.spacetelescope.org/images/opo9316a/|website=www.spacetelescope.org|accessdate=25 February 2017}} 5. ^1 {{cite web|title=New General Catalog Objects: NGC 1700 - 1749|url=http://cseligman.com/text/atlas/ngc17.htm#1741|website=cseligman.com|accessdate=25 February 2017}} 6. ^1 {{cite journal|last1=Johnson|first1=Kelsey E.|last2=Vacca|first2=William D.|last3=Leitherer|first3=Claus|last4=Conti|first4=Peter S.|last5=Lipscy|first5=Sarah J.|title=The Very Young Starburst Merger System NGC 1741*|journal=The Astronomical Journal|date=1 April 1999|volume=117|issue=4|pages=1708–1724|doi=10.1086/300800|language=en|issn=1538-3881}} 7. ^{{cite journal|last1=Conti|first1=Peter S.|last2=Leitherer|first2=Claus|last3=Vacca|first3=William D.|title=Hubble Space Telescope Ultraviolet Spectroscopy of NGC 1741: A Nearby Template for Distant Energetic Starbursts*|journal=The Astrophysical Journal Letters|date=20 April 2017|volume=461|issue=2|doi=10.1086/310005|language=en|issn=1538-4357}} 4 : Interacting galaxies|Eridanus (constellation)|NGC objects|Arp objects |
