   This feature photo captures several  atmospheric optical phenomena
   and night sky objects in the sky over  Kolkata, India. Most
   prominently, two types of lunar halos are visible, a  9 degree
   odd-radius and  22-degree halo. Both lunar halos are a product of
   light  refraction and reflection from ice crystals in the
   atmosphere. As their names imply, lunar halos are described by their
   apparent radii around the  Moon. In addition to the lunar halos,
   several additional objects seen in the night sky included the
    Pleiades approaching a near-conjunction with Moon, rise of the
    "hunter" Orion constellation, and an  airplane contrail that
   appears to cross the lunar halos. Overall, this photo shows a busy
   night sky with a lot going on all at once!
