WISEP J180026.60+013453.1 (designation is abbreviated to W1800+0134) is a brown dwarf of spectral class L7.5, located in constellation Ophiuchus at approximately 29 light-years from Earth. ==Discovery== WISEP J180026.60+013453.1 was discovered in 2011 by Gizis et al. from data, collected by Wide-field Infrared Survey Explorer (WISE) Earth-orbiting satellite — NASA infrared-wavelength 40 cm (16 in) space telescope, which mission lasted from December 2009 to February 2011. There are also precovery identifications of this object in Two Micron All-Sky Survey (2MASS) data (observed on 2000 September 23) and in the 3rd release of the database (close in time to the 2MASS observation). On 2011 June 22 Gizis et al. had conducted near-infrared spectroscopy with SpeX spectrograph, mounted on the 3 m Infrared Telescope Facility (IRTF), located at the Mauna Kea Observatory in Hawaii. In 2011 Gizis et al. published a paper in The Astronomical Journal, where they presented discovery of a newfound by WISE L-type brown dwarf WISEP J180026.60+013453.1 (a single discovery, presented in the article).
