Nobody looks up like amateur astronomers
Promoting Cooperative Solutions for Space Security
Comets – Named after discoverers
 McNaught, Shoemaker-Levy, etc.
Asteroids – Named by discoverers for others
 26858 Misterrogers
Globe@Night – Light pollution studies
Extrasolar planets, Supernovae, Gamma Ray Bursts, etc.
 Amateurs routinely do work of paid professionals
Comet McNaught – Akira Fujii 2007
Astronomy is now more democratic than ever
 Observational/computer technology increasingly available and affordable
 More widespread science education leads to more high-tech workers
 More high-tech workers leads to more widespread science education
 Formal and informal education by amateur astronomers
"In this golden age of technology, amateur astronomers are being recognized by the
professional community for their contributions.“

Jupiter Impact
Promoting Cooperative Solutions for Space Security
“By about midnight… I was ready to quit. Indeed I had hovered the mouse over the exit button…
I noticed a dark spot rotating into view in Jupiter’s south polar region… Eventually I stopped imaging and
went up to the house to start emailing people, with this image above processed as quick and dirty as possible
just to have something to show.” – Anthony Wesley, Observation Report (http://jupiter.samba.org/jupiter-impact.html)

Meteor Observations
Promoting Cooperative Solutions for Space Security
International Meteor Organization (http://www.imo.net/)
Founded in 1988 , more than 250 members worldwide.
Meteor showers and relation to comets and interplanetary dust.
“Amateur Astronomers See Perseids Hit the Moon”
Lunar studies and relation to astronaut safety
George Varros & Robert Spellman used home equipment in different locations to
record Perseid meteors strike lunar surface on 9 August 2008.
LunarScan - computer program written by amateur astronomer Pete Gural
searches digital video of the Moon for split-second flashes – not used here.
"This shows how amateur astronomers can contribute to our research," points out
Rob Suggs [NASA Meteoroid Environment Office ]. "We can't observe the Moon
24-7 from our corner of the USA. Clouds, sunlight, the phase of the Moon—all
these factors limit our opportunities. A global network of amateur astronomers
monitoring the Moon could, however, approach full coverage.“(Science@NASA, 2008)
Google Earth 4D Ionosphere Tool Aids Amateur Observers
Meteor showers and relation to Earth’s atmosphere
Tammy Plotner used home equipment, Google Earth tool, and publicly accessible
scientific data to compare atmospheric data with observed Perseid meteor
shower on 11-12 August 2008.
Watch how meteors create “intense areas of ionization “ in Earth’s ionosphere
in almost real time. (UniverseToday.com, 2008)

Fireball “Don’t Ask, Don’t Tell”
Promoting Cooperative Solutions for Space Security
Early-mid 2009:
United States government adopted policy to classify fireball data gathered by
classified military satellites (http://www.space.com/news/090610-military-fireballs.html)
 Scientists have relied on data from these satellites for past 15 years
 Data from unclassified satellites is still OK to share
 Affects US military satellite data only
 Amateur observations are now more important to help confirm scientific research
as well as eyewitness accounts from untrained persons

2008 TC3
Promoting Cooperative Solutions for Space Security
2008 TC3 is the first and only object to be:
 Seen approaching Earth as an asteroid
 Observed as a meteor
 Located and recovered as meteorites
Truly global effort:
Within 19 hours, > 1100 astrometric &
photometric observations conducted and
reported to Minor Planet Center in US.
 Amateurs provided positional data/images
 25 Minor Planet Electronic Circulars
within 11 hours as orbital data was refined
 Meteor entry seen by Meteosat-8 satellite
and by KLM Airline crew over Europe
 Meteorite fragments discovered and
collected by students at University of Khartoum,
Sudan
www.SecureWorldFoundation.org

Airline pilots saw flash of entry:
"… a KLM airliner, roughly 750 nautical miles
southwest of the predicted atmospheric impact
position, has observed a short flash just before
the expected impact time 0246 UTC. Because of
the distance it was not a very large
phenomenon, but still a confirmation that
some bright meteor has been seen in the
predicted direction.”

Galaxy Zoo – Green Peas
Promoting Cooperative Solutions for Space Security
“Murmurs of a potential discovery began when a group of volunteers who called themselves the
‘Peas Corps’ and the ‘Peas Brigade’ started a discussion in an online forum about a group of
strange bright green objects. The original forum thread was called ‘Give peas a chance.’
“The volunteers – many of whom had no previous astronomy background or experience – were
asked to refine their image samples and submit them to a lab for color analysis…
“ ‘No one person could have done this on their own,’ said [Carolin] Cardamone [Sloan Digital
Sky Survey] . ‘Even if we had managed to look through 10,000 of these images, we would
have only come across a few Green Peas and wouldn't have recognized them as a unique
class of galaxies.’ ” http://www.space.com/scienceastronomy/090727-green-peas.html

“It's amazing what amateurs are doing with planetary images these days. Using calibrated
data archived in the Planetary Data System, or even the preliminary raw images posted on
the Cassini or MER web sites, they are generating color images and mosaics that eclipse in
detail and sheer beauty the best that professionals could have produced a decade ago.”
