SOHO 1000th Comet Contest
The SOHO 1000th Comet
Predict the date and time that SOHO 1000th -a comet yet to be
discovered- will make its closest approach to the Sun (perihelion).
However, names will be posted periodically to verify that an entry has been received on your
- The contest is open to anyone, anywhere, except those administering the contest.
- Entries can only be submitted using this form.
- Entry submission will closeafter the discovey of Comet 960.
- Entries without a name and valid e-mail address will be discarded.
- Only one entry per person will be accepted.
- In the case of the 1000th comet being an archive discovery, then the
discoverer is also not eligible, but the closest guess still wins.
- Guesses will not be publicized until the entry period has closed.
THE CONTEST IS CLOSED!

of the Visitor Center staff. (Note: this prize does not include any transportation or
lodging costs to and from Greenbelt, MD.)
Second and third place entries will receive a package

viewing glasses, and a selection of SOHO materials.
Tips: Possible Strategies
- Estimate the number of comets per year and extrapolate.
- Refine your estimate by looking at the monthly variation in the rate of discoveries.
- Consider the chance that the discovery will be an archive claim.

Notes & Disclaimers
- Determination of the SOHO comet numbers is entirely at the discretion of Karl Battams. He assigns the numbers in order of discovery. These numbers are not an official
product of any recognized astronomical body. However, they are a very convenient way to
refer to the various comets and to keep track of the total number.
- Definition of an archive discovery: This is also at the discretion of Karl Battams. If a comet is reported more than 36 hours after it is first visible in the data
(and there are no large gaps in the data), then the comet will be designated as an archive
claim. In cases of ambiguity, the 36 hour rule will begin at the time when an average
observer might be expected to have been able to find the comet.
- Neither ESA, NASA, or any other institution associated with SOHO is involved with the
adjudication of claims or providing the prize. The contest is designed to increase the
public's awareness of SOHO's discoveries and demonstrate the ease of accesibility of
scientific data sets by the general public.
