**NGC 5530** is a [spiral galaxy](/source/Spiral_galaxy) located in the constellation [Lupus](/source/Lupus_(constellation)). It is located at a distance of about 40 million [light years](/source/Light_year) from Earth, which, given its apparent dimensions, means that NGC 5530 is about 60,000 light years across.[1] It was discovered by [John Herschel](/source/John_Herschel) on April 7, 1837.[3]

NGC 5530 is a member of the NGC 5643 Group, named after [NGC 5643](/source/NGC_5643).[4]

## Characteristics

NGC 5530 has a flocculent spiral pattern, with multiple [spiral arms](/source/Spiral_arm) and spiral fragments with many knots.[5][6] Dust lanes associated with spiral arms are visible across the disk.[5] The galaxy has a small [nucleus](/source/Galactic_nucleus)[5] with a magnitude 13 field star superimposed. In [H-alpha](/source/H-alpha) images some faint [HII regions](/source/HII_region) are visible, but are hard to distinguish among the starry field.[7] In blue filter the galaxy has an inner pseudoring which has a diameter of 4.6 kpc and accounts for 14% of the total H-alpha emission of the galaxy. The star formation rate of the galaxy is estimated to be 1.0±0.4 [*M*☉](/source/Solar_mass) based on H-alpha emission.[8] In the nucleus lies a [nuclear star cluster](/source/Nuclear_star_cluster) which has a radius of 2.6 arcseconds.[9]

## Supernova

One [supernova](/source/Supernova) has been discovered in NGC 5530, SN 2007it. It was discovered visually by [Robert Evans](/source/Robert_Evans_(astronomer)) on 13 September 2007 at an [apparent magnitude](/source/Apparent_magnitude) of 13.5, lying 24" west and 25" north of the nucleus.[10] It was determined spectrographically as a young [Type II supernova](/source/Type_II_supernova).[11] Further observations lead to its Type IIP categorisation. There are indications that dust was formed during the supernova, as well as of a [light echo](/source/Light_echo). The progenitor star had an estimated mass of 16–27 M☉.[12] A search of archival photographs revealed several taken by the [All Sky Automated Survey](/source/All_Sky_Automated_Survey), including one taken on 6 September 2007.[13] In this image, it was magnitude 12, making SN 2007it the brightest supernova of the year 2007.[14]
