The excess thermal energy stored in the upper jovian stratosphere was 3 +3-1.5× 10 26erg over the L site, and 2 +2-1× 10 26erg over the K site at the time of the observations.
The older K site was still 30 ± 5 K warmer than the surroundings at the 10-mubar level. The L site temperature increased by 80 ± 10 K at 5 mubar, but did not exceed 20 K around 1 mbar or 10 K around 10 mbar. The intensity distribution between strong and weaker CH 4lines implies that the stratospheric heating was primarily confined to pressures less than 500 mubar. Stratospheric heating was detected from strong enhancements of methane emission near 8.1 mum over areas at least 15,000 km wide around the K site observed 23 hr after impact and around the L site 11 hr after impact. Asteroid 3673 is named after him.We present high-resolution 8-14 mum observations of Shoemaker-Levy 9 sites conducted on July 20, 30, UT at the NASA Infrared Telescope Facility. He was also the recipient of four honorary doctoral degrees and is Honorary President of the Montreal and Kingston centres of the Royal Astronomical Society of Canada. In 1998, Levy also received an Emmy Award for co-writing the documentary Three minutes to impact for the Discovery Channel. Haas Award from the Association of Lunar & Planetary Observers in 1990 the Amateur Achievement Award from the Astronomical Society of the Pacific in 1993 two Group Achievement awards from NASA in 19 the Simon Newcomb Award from the Royal Astronomical Society of Canada in 2002 and the Benjamin Franklin Citizen Award from the Society for Amateur Scientists in 2003. Bruce Blair Award from the Western Amateur Astronomers and the Walter H. Peltier Award from the Astronomical League in 1988 the G. Barnard Award from the Western Amateur Astronomers and the Leslie C. He has received more than 20 awards, including the Chant Medal from the Royal Astronomical Society of Canada in 1980 the E. Over the years, he has developed numerous educational programs in astronomy for young people and the general public. Today, he is the discoverer or co-discoverer of 21 comets and more than 225 asteroids, including the famous Shoemaker-Levy 9 comet that crashed into Jupiter in 1994.Īuthor or editor of more than thirty books, numerous articles and more than 1,000 lectures and interviews, Levy is also involved with a number of magazines: he is Science Editor of Parade (USA), Associate Editor of Sky & Telescope (USA), and a regular contributor to SkyNews (Canada). In 1984, after 19 years of fruitless searching, he discovered his first comet. By the end of the 1980’s, he was the most prolific observer in the American Association of Variable Star Observers with more than 10,000 observations per year for meteors, variable stars and Messier objects.Īlways looking for a better climate and a darker sky, he moved to Arizona in 1980 where he still lives today. In 1965, he began to search for novae and comets in the sky. Levy’s interest in astronomy began during a partial eclipse of the Sun in 1959 at the age of 11. He is currently writing his doctoral degree at the Hebrew University in Jerusalem, still on the subject of English literature. He obtained his bachelor’s degree in 1972 from Acadia University in Wolfville, Nova Scotia, and his master’s degree in 1979 from the University of Queen’s in Kingston, Ontario. Davy Howard Levy was born in 1948 at Montréal, Quebec.
