between the right foot of Hercules, the left hand of Boötes, and the constellation Draco, was formed by La Lande in 1795, as a souvenir of the instrument with which he and his nephew, Michel Le Français, observed the stars subsequently incorporated under this title into the latter's Histoire Celeste Française.
It is the Mauer Quadrant of Stieler's Planisphere, and the Quadrante of the Italians, but is not figured by Argelander or Heis, nor recognized by modern astronomers.
It comes to the meridian with β Ursae Minoris on the 19th of June.
A rich meteor stream, the Quadrantids, radiates from this group on the 2d and 3d of January.
Images with borders lead to more information.
The thicker the border, the more information. (Details here.) |
