Characteristics

           Eridianus, is an enormous constellation that includes an ample zone that goes from the equator to 60º of South latitude, analogous, from the geographic point of view with Chile. It is observed completely during the summer in the South hemisphere and the equatorial zone in the North hemisphere in you solely cold nights of winter next to Orion. It limits the north with Orion, Taurus and Cetus, to the east with the following constellations ordered of north to the south: Cetus until 20º of South latitude, Fornax until -40º and Phoenix until -60º. To the south limits with the circumpolar constellation of Hydrus with a southern latitude of 60º and to the west with the constellations Horologium until -40º of latitude, Caelum until -25º, Lepus until -10º of South latitude and again Orion.

        Eridianus I located the 12 of November of 1984 from the locality of Inca, Majorca, Spain to it. The constellation that I located corresponds to its structure until 50º of visible South latitude from where I write to you, logically, the star most shining of the constellation or Achernar of magnitude 0.5 I have not been able it to observe to date.

Observations by telescope

         NOTE: One is in a rich zone; one is one weak double of brightness, slightly separated and unfolding itself with 50x; the main one is white, however, the secondary one is bluish.

          NOTE: One is in a poor zone; a small difference of magnitude exists, are little separated, its colors are similarities, is one pretty double and easy to identify, it is unfolded with 50x.

            NOTE: One is in a very poor zone; in the field there are approximately ten stars, is a slight difference of magnitude, are separated, easy to locate is unfolded with 50x.

         NOTE: One is in a poor zone; there is a remarkable difference of magnitude, are very together, his phantoms are different, the main one is reddish, however, the secondary one is bluish, easy to identify is unfolded with the eyeglass of 100x.

            NOTE: One is in a poor zone; there is a great difference of magnitude between the components, his phantoms are different, the main one is red, in change, profit not to identify the color of the secondary one, I have the impression that she is bluish, although am not del all insurance, easy to locate is unfolded with the eyeglass of 50x.

                NOTE: One is in a zone, very very poor; in the field there are approximately five stars; there is a remarkable difference of magnitude, are separated, his colors are similarities, is most shining of the field, therefore, it is identified without difficulty, it is unfolded without difficulty with 50x.

             NOTE: One is in a rich zone; there is a remarkable difference of magnitude, are separated, the main one is orange, however, the secondary one, is bluish; it is unfolded without difficulty with the eyeglass of 50x.

            NOTE: One is in a rich zone; there is a smallest difference of magnitude, the main one is bluish, however, the secondary one is orange, easy to locate is unfolded with the eyeglass of 50x.

           NOTE: One is in a rich zone; there is a small difference of magnitude, are together, his colors are similarities, easy to locate is unfolded with 50x.

        NOTE: One is in a poor zone; there is a small difference of magnitude, are together, is most shining of the field, therefore, it does not exist difficulty at the time of unfolding it with the eyeglass of 50x.
