  9. 9. Entire eclipse visible only from North America, Greenland, Iceland. </li></li></ul><li>WHY NOW?<br /><ul><li> Eclipses are relatively rare (0 to 3 per year worldwide, not all visible from here), total eclipses even rarer.
  10. 10. Occurs on same day as winter solstice (moon at maximum northern position in its orbit)
  11. 11. Mid-Eclipse Coordinates: Azimuth 264° 24’; Altitude 41° 8‘</li></ul>“The three dimensional reality of our universe comes alive in a graceful celestial ballet as the Moon swings through the Earth's shadow.“<br />
  12. 12. Object #2: Orion Nebula<br />
  13. 13. BACKGROUND INFORMATION<br /><ul><li>Galileo observed a grouping of stars in the trapezium region of the Orion Nebula and from his sketches, we are able to see that the grouping of stars is in fact the Orion Nebula.
  14. 14. The Orion Nebula’s glowing gas surrounds stars at the edge of a huge interstellar molecular cloud 1500 light years away.
  15. 15. The stellar winds from stars create bubbles and arcs and bowl shaped appearances.
  16. 16. Next time you view the Orion Nebula, try to notice the three star belts and star hanging from the belt.</li></li></ul><li>WHY NOW?<br /><ul><li>The Orion Nebula is going to be amazingly interesting to see in December because this is the best month to see it.
  17. 17. The Orion Nebula is the best and easiest thing to observe through a telescope.</li></li></ul><li>Object #3: Geminids Meteor Shower<br />

  23. 23. Appeared suddenly in the early 1860’s
  24. 24. Number of meteors have increased from about 14 meteors per hour when first observed to 50-80 meteors per hour now</li></li></ul><li>WHY NOW?/HOW TO LOCATE<br /><ul><li>Geminids occur this time of year, when Earth passes through the trail left by a comet as it passed by our orbit
  25. 25. Meteors from the Geminids can begin to be seen around Dec. 6th
  26. 26. Peak is on the night of Dec. 13th
