Notable Observations and Accomplishments

  • Conducted a survey of meteorites and micrometeorites at and near the South Pole and on the Union Glacier in the Ellsworth Mountains of Antarctica as part of the 2011 Expedition to Antarctica and during return expedition of Janurary 2013.

  • Observed shadow bands during the 2010 July 11 and 2012 Nov 14 Total Solar Eclipses.

  • Published "The Instability of Jupiter's Moons", Sky and Telescope, April 2010, Pages 30-31.

  • Searched for Vulcanoid asteroids during the Libya 2006 Total Solar Eclipse Expedition, the Gobi China 2008 Total Solar Eclipse Expedition, and the Enewetok 2009 Total Solar Eclipse Expedition.

  • Presented "The search for Vulcanoid Asteroids at the Solar Eclipse Conference 2007 (SEC 2007).

  • Published "The search for Vulcanoid asteroids" (Sky and Telescope, Jan 2006, Pages 87-89) to encourage amateur astronomers to search for vulcanoid asteroids during total solar eclipses. Note that the link to the article is a revised version (2008 May) of the original article and is available by the kind permission of Sky and Telescope.

  • Calculated the mean Sun/Earth distance - using the 2nd & 3rd contact timings of the 2004 June 8 Transit of Venus
    149596765 km ± 3543 km (0.0237% uncertainty) - AU error (ΔAU): 2437 km (0.0016%)
    Solar parallax (Π): 8.79432" ± 0.00018" (0.0020% uncertainty) - parallax error: (ΔΠ) 0.00010" (0.0011%)

  • Confirmed Henry Norris Russell's 1874 claim that a transit spot can be seen on Venus during transit -
    Sky & Telescope: Nov 2004, p.80

  • Detailed analysis of the F0V star HD 354069 -
    1.6 solar mass, 1.77 solar radii, 407 parsecs - 2004 Aug 28

  • Demonstrated that it is possible to observe a 0 second old new moon -
    Observed the surface of the moon during middle of 2003 Nov 23 Total Solar Eclipse over Antarctica
    Obtained the record for the sighting of the youngest moon possible -
    Observed 0 second old during middle of 2003 Nov 23 Total Solar Eclipse over Antarctica: Sky & Telescope: May 2004, p.121

  • First to report that a fire Destroys the Mt. Stromlo Observatory to Sky & Telescope: January 19, 2003 and helped raise donations for the Mt. Stromlo Redevelopment and Bushfire Relief fund.

  • Coined the term meteor squall to describe a significant but not quite storm level meteor shower -
    Sky & Telescope: March 2002, p.102

  • Leonid 2001 meteor squall -
    Observed Peak count of 2408 count/hr at the Fremont Peak Observatory

  • Observed effect of the 1999 Aug 11 total solar eclipse on ants -
    Sky & Telescope: Nov 1999, p.122

  • Sighted impact fireball of Comet Shoemaker-Levy 9 Fragment R Collision with Jupiter -
    Fremont Peak Observatory, 1994 July 21

  • Visual identification of the Crab Nebula Pulsar -
    Fremont Peak Observatory, 1987

  • Observed Supernova 1987A from Canberra Australia on 1987 Feb 24 (20 hrs after discovery) -
    Observed color change and an increase in brightness

  • Measured timing on numerous Total, Annular & Partial Solar Eclipses -
    Also recorded temperature changes, wind direction changes, sky condition changes
    during partial phases.

  • I have observer the following solar eclipses (total, annual, hybrid, partial):

    • 1970 Mar 07 - USA (total)
    • 1972 Jul 10 - USA (partial)
    • 1974 Dec 13 - USA (partial)
    • 1977 Oct 12 - USA (partial)
    • 1979 Feb 26 - USA (total)
    • 1980 Aug 10 - USA (partial)
    • 1984 May 30 - USA (annular)
    • 1989 Mar 07 - USA (partial)
    • 1991 Jul 22 - USA (total)
    • 1992 Jan 04 - USA (annular)
    • 1993 May 21 - USA (partial)
    • 1994 May 10 - USA (annular)
    • 1999 Aug 11 - Turkey (total)
    • 2000 Dec 25 - USA (partial)
    • 2001 Dec 14 - USA (total)
    • 2002 Dec 03 - Australia (total)
    • 2003 Nov 23 - Antarctica (total)
    • 2006 Mar 29 - Libya (total)
    • 2008 Aug 01 - China (total)
    • 2009 Jul 22 - Enewetok (total)
    • 2010 Jul 11 - French Polynesia (total)

    As of
    $Date: 2013/02/17 03:00:00 $
    above list includes 2187.3 seconds of totality!

    Thankfully, (and by careful site selection and paying attention to the weather) I have not been clouded out on any eclipse. In fact, with the exception of a few seconds at 2009 Jul 22 - Enewetok, and a few seconds at 2009 Jul 22 - Enewetok, I had not had any totality time impacted by coulds.

  • Tracked outer moons of Jupiter, Saturn & Uranus -
