Regulus is the brightest star in the constellation Leo.  Click back to my website and look for the page "Regulus in Leo" under the science page.  On this larger image it will be easier to spot the declination numbers on the vertical sides and the right ascension numbers on the horizontal sides.  Regulus is at the bottom of the backwards question mark which forms the front and head of the lion.  Give the declination to the nearest degree and the right ascension to the nearest hour.  (Remember that the declination will be a positive number because Leo is north of the celestial equator.)  Note that declination is like latitude on earth and that right ascension is like longitude except it is measured in hours from right to left.  (I apologize for disappointing those who were eagerly awaiting fresh questions during the Christmas holiday.  I will count answers for this one double and enter them as first term grades.)
