Meteorite spotting - not an exact science 1 by Andrew Bevan The meteorite swarm called the Perseides reaches its maximum this evening on the night between the 12th and 13th of August. So astronomers roar with highpitched voices that we should position us in deckchairs and let the night pass as we enjoy a spectacular display of celestial fireworks. But we should have to realize that astronomy on this level is in fact not an exact science. Astronomers know that the earth will pass through a band of particle rubble, which consists of the remains left behind in the orbit of a long past comet, however, the astronomers do not know whether the comet remains actually are there. I've been on the hillsides on several previous occasions, allying with expectant astronomers, only to experience that numbers of actual meteorites was anything but spectacular. "But we can't really know", they say. "We know is that there is a higher likelyhood of hitting a particle swarm, but it is impossible to say whether the grit is there and meteorites actually will occur or not." Many small particles enter the earth's atmosphere and remain invisible to the eye, but the occasional pebble or rock will enter and leave a marvellous trail across the sky or even an explosion. Maybe astronomer and astronomers should join hands. Maybe astrologers could predict whether mother Earth hits the dust and fireworks fall down from the Sky. The Sun opposite Jupiter and sextile Mars gives me the hope of fireballs and action. The Sun is also semi-sextile Saturn, who is square Mars, which suggests a gest of accompanying friction. The Moon in Taurus does past midnight cast her antiscia to the Sun. So maybe I shall put on a coat and go outside and enjoy the evening with the Scotch. The best time for meteorite observation is prior to dawn. At midnight the Earth is shielding herself from meteorite bombardment, but as dawn comes near she turns into the particle drift and is fully exposed. Astronomer are hoping for a spectacular show, or at least they wish! http://www.astronor.com Quote Wed Aug 12, 2009 3:42 pm
