Arktur (α Bootis) - "The Guardian of the Bear" is the brightest star in the northern sky and the fourth brightest overall (0.0 mag) after Sirius, Canopus, and Alpha Centauri. It is aimed at by a fourfold extended line connecting the stars of the Big Dipper downwards. Arcturus is the closest orange giant, located 35 light-years away with a diameter of around 30 million kilometers. It is 20 times larger than the Sun, but its luminosity exceeds it by up to 100 times.
Izar (ε Bootis) - Mirak or Pulcherrima - "beautiful". The second brightest star in the constellation is a beautiful double star in at least a 10 cm telescope, consisting of an orange component (2.7 mag) and a blue component (4.9 mag) creating a color contrast, with a separation of 2.9". However, you will need higher magnification and a calm night. The distance of the system is 200 light years.
Alkalurops (μ Bootes) - easily distinguishable triple stars. Besides the main yellow component (4.5 mag), we will see a companion at a distance of 108.3" with a magnitude of 7.1, which, when observed with at least an 8 cm telescope, will split into two stars of approximately half a magnitude difference (7 mag and 7.6 mag) (orange and yellow, separated by 2.3").
ξ Boo - A close binary star, with components of 4.8 magnitude (yellow) and 6.9 magnitude (red-orange), which have a mutual orbital period of 149 years. Since 1980, when they reached their maximum separation (7.2"), their separation has gradually decreased and currently reaches approximately 6". At the closest separation of 1.8" (last observed in 1918), the companion star is lost in small telescopes. The system is located 22 light-years away. In the field of view, at a distance of 99", another star HR 5553 (magnitude 6) usually appears, but it is not related to this system in any way.
ν Boo - A binary star distinguishable by the naked eye, consisting of an orange and yellow-white component with a separation of 14'. Both stars have an approximate magnitude of 5.
T Borealis - In April 1860, an unknown star with a magnitude of 9.7, later designated as T Borealis, was observed in the same field of view as Arcturus. Since then, no one has seen it, but it is not excluded that it may still reappear. It is believed to be a recurrent nova or an irregular variable star. Its position is 14:11 minutes, +19.18.
Please note that the abbreviations for cardinal directions (N, W, S, E) should not be translated into their word equivalents. The combinations of cardinal direction abbreviations should always be translated into combinations of abbreviations in English, for example, ZSJ should be translated as WNW, VJV as ESE, JV as SE, ZJZ as WSW, VSV as ENE, SZ as NW, JJZ as SSW, SSV as NNE, SV as NE. The abbreviation for IAU constellation code should not be translated. "Boční vidění" should be translated as "averted vision".
