WISEP J190648.47+401106.8 (shortened to W1906+40) is a L-dwarf star. In 2015 it was shown to have on its surface a storm the size of Jupiter's Great Red Spot. The storm rotates around the star roughly every 9 hours and has lasted since at least 2013, when observations of the storm began.[2]
The star is 53 light-years from Earth, has an intrinsic brightness .0002 that of the sun (10−3.67±0.03L⊙), a radius of 0.9 Jupiters, and a surface temperature of 2,038 °C. The star emits significant flares.[1][3][4]
Distance 53.3 (+1.17, -1.11) light years.[4]
