Lyrid Meteor Shower (April 22, pre-dawn) -- South sky up to 20 meteors per hour visible

from Almanac dot-com (Old Farmer's Almanac):

  • Which seasons? The time of the year for each shower is determined by when in Earth’s orbit it crosses the stream of meteoroids.
  • Note that the “best” viewing times are usually predawn and late evening. In nearly all showers, the radiant is highest just before dawn. (The Geminid meteor showers are visible all night long, since Gemini arises just an hour or two after nightfall; the radiant is highest a little after midnight.) Sporadic meteors (unrelated to a shower and commonly called shooting stars) can be seen on any night, but increase in frequency after midnight and peak just before dawn.
  • Starting around midnight, your location on the globe spins around to the forward-facing half of Earth (in relation to the direction of orbit). At dawn, your location on the globe directly faces the direction in which Earth is traveling along its orbit. So between midnight and dawn, you’ll be viewing the meteors head-on, for a more frequent display.
  • You don’t need any special equipment. In fact, binoculars do not work for meteor showers. The naked eye is best.
  • Spread a blanket on the ground and look up in the dark night sky.
