The 2% dip event was named 'Elsie' (a homophone of 'LC', in reference to Las Cumbres and light curve). More generally the astronomical community was described as having gone 'mildly bananas' over the opportunity to collect data in real-time on the unique star.

By the end of the three-day dimming event, a dozen observatories had taken spectra, with some astronomers having dropped their own projects to provide telescope time and resources. Furthermore, the independent SETI projects Breakthrough Listen and Near-InfraRed Optical SETI (NIROSETI), both at Lick Observatory, continue to monitor the star. Observations from multiple observers globally were coordinated, including polarimetry. Further optical and infrared spectroscopy and photometry were urgently requested, given the short duration of these events, which may be measured in days or weeks. This was verified by the Fairborn Observatory (part of the N2K Consortium) in Southern Arizona (and later by LCO Canary Islands).

It was detected by the Las Cumbres Observatory Global Telescope Network, specifically by its telescope in Maui (LCO Maui). On, Boyajian and her colleagues reported, via The Astronomer's Telegram, on an ongoing dimming event (named 'Elsie' ) which possibly began on.

During its primary and extended mission from 2009 to 2013 it continuously monitored the light curves of over 100,000 stars in a patch of sky in the constellations Cygnus and Lyra. The main source of information about the luminosity fluctuations of Tabby's Star is the Kepler space telescope. The star was cataloged in the Tycho, 2MASS, UCAC4, and WISE astronomical catalogs (published in 1997, 2003, 2009, and 2012, respectively).

Tabby's Star was observed as early as the year 1890. With an apparent magnitude of 11.7, the star cannot be seen by the naked eye, but is visible with a 5-inch (130 mm) telescope in a dark sky with little light pollution. While only a few arcminutes away from the cluster, it is unrelated and closer to the Sun than it is to the star cluster. Tabby's Star is situated south of 31 Cygni, and northeast of the star cluster NGC 6866. Tabby's Star in the constellation Cygnus is roughly halfway between the bright stars Deneb and Delta Cygni as part of the Northern Cross.

In the infrared Two Micron All-Sky Survey (2MASS), the star is identified as 2MASS J20061546+4427248. In the Tycho-2 Catalogue, an enhanced collection of stars catalogued by Hipparcos, the star is known as TYC 3162-665-1. In the Kepler Input Catalog, a collection of astronomical objects catalogued by the Kepler space telescope, Tabby's Star is known as KIC 8462852. Other designations in various star catalogues have been given to Tabby's Star. The star has also been given the nickname 'LGM-2' – a homage to the first pulsar discovered, PSR B1919+21, which was given the nickname ' LGM-1' when it was originally theorized to be a transmission from an extraterrestrial civilization. The nickname 'WTF Star' is a reference to the paper's subtitle 'where's the flux?', which highlights the observed dips in the star's radiative flux. Boyajian, who was the lead author of the scientific paper that announced the discovery of the star's irregular light fluctuations in 2015. The names 'Tabby's Star' and 'Boyajian's Star' refer to American astronomer Tabetha S. Tabby's Star is not the only star that has large irregular dimmings, but other such stars include young stellar objects called YSO dippers, which have different dimming patterns. In September 2019, astronomers reported that the observed dimmings of Tabby's Star may have been produced by fragments resulting from the disruption of an orphaned exomoon. Several hypotheses have been proposed to explain the star's large irregular changes in brightness, but none to date fully explain all aspects of the curve. The discovery was made from data collected by the Kepler space telescope, which observed changes in the brightness of distant stars to detect exoplanets. Unusual light fluctuations of Tabby's Star, including up to a 22% dimming in brightness, were discovered by citizen scientists as part of the Planet Hunters project. A distant red dwarf companion has been reported, making Tabby's Star a binary stellar system.

Tabby's Star (also known as Boyajian's Star and WTF Star, and designated KIC 8462852 in the Kepler Input Catalog) is an F-type main-sequence star in the constellation Cygnus approximately 1,470 light-years (450 parsecs) from Earth. Tabby's Star in infrared (left) and ultraviolet (right)
