WHAT IS THE SUNGRAZER PROJECT?

A NASA-funded Citizen Science Project that enables anyone in the world to become a comet discoverer!

HOW DOES IT WORK?

Participants download the latest images from the ESA/NASA Solar and Heliospheric Observatory (SOHO), or NASA Solar Terrestrial Relations Observatory (STEREO) spacecraft missions, and look for moving objects. These objects are submitted as reports to this website, and are reviewed by the Project Administrator so determine if they are real and if they are a new object.

HOW CAN I JOIN? WHERE DO I BEGIN?

First, we encourage all new participants to carefully read the Guide. You should also take a look at the SOHO Website and get familiar with the LASCO C2 and LASCO C3 images (that's where nearly all of the comets are discovered). Finally, send an email to the Sungrazer Project Administrator - sungrazer@nrl.navy.mil - requesting to join the project. You are encouraged to also email any questions you have about the project.

HOW WILL MY PARTICIPATION CONTRIBUTE TO SCIENCE?

Well over half of all known comets have been discovered via the Sungrazer Project! Your discoveries help drive a huge variety of scientific research, including studies of comet orbits, families, composition, dust properties, evolution and fragmenting. Sungrazer discoveries have also been used to benefit heliophysics (studies of the Sun), as we watch comets plunge through the Sun's atmosphere like small solar probes. Project discoveries have led to dozens of scientific research papers, contributed to several PhDs, and inspired enthusiasts as young as 13 years old to pursue astronomy careers!
