An asteroid said to be approximately 1 mile in diameter will have a near encounter with the Earth at 11 pm Pacific Daylight time today, Saturday, 31 March.  The rock will pass within 3,900,000 kilometers of our planet.  The asteroid is passing south against the backdrop of the constellation Leo this very moment.  It is predicted to be 10th magnitude and will require a 6 inch telescope or greater to see. Its proximity to a nearly full moon will not help the seeing. This NASA JPL link will allow you to generate an ephemeris.  Spaceweather.com has a stereogram of the object passing the galaxy M81.
