English: The Spring Triangle between Arcturus (Bootes), Spica (Virgo, in May 2017 with Jupiter and, "incidentallly", the Moon) and Regulus (Leo); the dashed lines show how to find Arcturus and Spica from the handle of the Big Dipper (Part of Ursa Major, above) and how to find Regulus from the dipper. On top of the left side Corona Borealis, at the right the unimpressive Cancer and, for a better orientation, the stars Procyon, Pollux and Castor from the Winter Hexagon.
All stars of an apparent magnitude of at least 2 mag are labelled.
The dahed red lines show the equilateral spring triangle with Denebola instead of Regulus and a second equilateral triangle with Arcturus, Gemma and Seginus.
