On the first day of spring, 2009, astronomers at Geocache Observatory determined that an asteroid was on a collision course with Earth. The following facts were obtained:
1. The asteroid was sighted at an altitude of 90° above Geocache Observatory located at the coordinates N 29° 44.034 W 95° 22.483.
2. The asteroid missed Geocache Observatory due to the rotation of the Earth (15° per hour) and it hit west of Houston, Texas.
3. Constant laser ranging from initial sighting to impact indicated the asteroid had an average velocity of 38.185 Km/sec.
4. Sister Observatories A and B located on a level plain at N 30 22.184, W 094 38.348 and N 29 05.638, W 096 06.063 determined the angle formed between the asteroid and observatories at A and B, was 3.00° (See Diagram).
5. Satellite images of Earth suggested the trailhead of a possible path close to the asteroid could be found 0.26 kilometers from ground zero at a bearing of 289.5°. The photo shows the impact crater along with the remains of the asteroid.
If you are the first to ground zero you can claim the asteroid as a souvenir. A camouflaged cache capable of holding TBs and other small items is located 10’northeast of the impact crater. Inside the cache, the FTF will find instructions for further investigation of the asteroid and papers to log one’s find.
Hurry before the rain washes out the impact crater.
