Mythology and history

Arturus, name of the main star of Bootes determines the right knee of the mayoral mitológico, stars h, z and u represents the corresponding leg, whereas the weak stars and forms the right leg. The waist marks g and d ,the right shoulder star d and the left armpit to it the g. The head is where star b shines .     The ethimology of the name goes back to Arctos-oura, that means the tail of the Bear, and, in effect, the stellar situation of Arturus follows  the imaginary line of the tail of the Great Bear or the rudder of the Great Car remote. For that reason in the antiquity, Arturus represented the guardian of the bear or the watchman of the sky, whereas for the Hebrews it was the star of Job since it is mentioned to him in the book of the same name of the Sagradas Scriptures, chapter IX, versicle 9. Homero and Hesiod called the attention to the navigators on the star, attributing to him the signals that foretell storms.

Of the same subject it speaks centuries Virgilio in the Geórgicas later, (book I, verse 68), noticing the farmer who suspends the roturación of the fields when the star is reddish and high to the dawn.  Arturus comprises of a rich anecdotal history, for example, in 1635, it in the heat of observed light of the day with a telescope Jean Baptiste Morin, one of the last astrologers of the French cut; this one, hidden in the camera of queen Ana of Austria at the moment gives that it gave to light king Luis XIV the future who had become diligentemente horóscopo, needed to know the moment exact of the birth.     Arturus in addition, went the first star to which, uselessly and trusting its relative proximity, light is to 37 years, G. Piazzi tried to apply the methods of measurement of the parallax to determine its range which obtained Peters in 1842.     And finally, in the spring of 1933 the light of Arturus, opportunely located  by a telescope on a photoelectric cell, activated the automatic switch who ignited of blow all the illumination of the exhibition of Chicago, the U.S.A

Characteristics

    During the nights of April we can already observe Bootes that culminates high in the meridian its main star Arturus, precursor for the old ones of ominous events. Along with Spica de  Virgo and Denébola in the constellation of I read comprise of the celestial triangle of the spring for the inhabitants of the North hemisphere. For these it culminates almost during the primaverales nights in the zenith. Its form is extended beginning in 10º until 50º of North, visible latitude for more than six months from March to September in the North hemisphere and from April to June in the South hemisphere.

    It limits the north with the constellation of Draco and the Great Bear or Ursa Major, the east with Dogs Venatici and Coma; to the south with Virgo and the west with the constellations of Serpens Caput, Crown Borealis and Hercules.

    One is closely together of the galactic North Pole located in a the constellation of Comma, for that reason we observe in Bootes great amount of galaxies but very few shining stars as well as stellar accumulations, cloudy diffuse or planetary.

    The constellation of Bootes I located the February 28th, 1982, when it was  14 years old, I suppose that in one night cold of winter

Observations by telescope

NOTE: It is a quite weak galaxy, it costs enough to identify it, a smallest gray and round nubecita is observed.

NOTE: It is one very pretty double, it emphasizes the main one by its white color, and the secondary one with a darker color, is unfolded with the eyeglass of 50x, although the best spectacle we obtain it with the eyeglass of 200x.

NOTE: One is in a rich zone; it emphasizes by his beauty, the magnitude difference is remarkable and his colorful one to expectacular, the main one has a yellow color hard, however, the secondary one is red, is unfolded without difficulty with the eyeglass of 50x.

NOTE: One double is pretty, although their colors are not distinguished very well, is sufficient the separated thing to unfold it with the eyeglass of 50x, is a remarkable difference of magnitude between their components.

NOTE: One is in a poor zone; there is a small difference of magnitude, are united, the colors are identical, both are white, it is one pretty double, it is unfolded with the eyeglass of 50x.

NOTE: One is in a neither rich nor poor zone; there is a slight difference of magnitude between the components, both components are white, is unfolded with the eyeglass of 50x.

NOTE: One is in a very poor zone; there is a slight difference of magnitude between the components formed by main of red color and white the secondary one; it is one double very pretty, easy to locate is unfolded with the eyeglass of 50x.

NOTE: One is in a poor zone; there is a slight difference of magnitude, are slightly separated, easy to locate is unfolded with the eyeglass of 50x.

NOTE: One is in a partially poor zone; there is a remarkable difference of magnitude are slightly separated, profit not to find out the color of his components, identification is simple due to the magnitude from the main one, is unfolded without difficulty with the eyeglass of 50x.

NOTE: One is in a poor zone; there is a slight difference of magnitude, are enough meetings, is the one double weakest one than the previous ones, profit not to identify the colors of the components, is unfolded without difficulty with the eyeglass of 50x.

NOTE: One is in a poor zone; there is a small difference of magnitude, are excessively separated, the main one is white, however, the secondary one I see it bluish, easy to locate is unfolded with the eyeglass of 50x.

NOTE: One is in a zone, very very poor; there is a slight difference of magnitude, exactly of a unit, is essential the eyeglass of 100x to unfold it is easy from identification of the double, profit not to find out the colors.

    NOTE: One is in a partially rich zone; there is a smallest difference of magnitude, are slightly separated but the sufficient thing to be unfolded with the eyeglass of 50x, both components I see white them, is one very pretty double.

    NOTE: One is in a relatively poor field; there is a remarkable difference of brightness between the components, the main one I see white it, however, the secondary one, is bluish, is unfolded with the eyeglass of 100x, is one very delicate double

    NOTE: One is in a poor zone; there is a slight difference of brightness between the components, are something tight, unfolding itself with the eyeglass of 50x, the main one is of the spectral type N, the secondary one seems to see it to me white.

    NOTE: One is in a poor field; there is a remarkable difference of brightness between the components, are something separated unfolding itself with the eyeglass of 50x, the main one seems to see it to me white, however, I do not identify the color of the secondary one

    NOTE: One is in a partially poor zone; there is a small difference of brightness between the components of white color and blue, it is unfolded without difficulty with the eyeglass of 50x.

    NOTE: One is in a rich zone; there is a remarkable difference of brightness between the components, both I see them of yellow color, is unfolded without difficulty with the eyeglass of 50x
