How to detect asteroids(Yebes -SPAIN, June 9th 2003)
1º Two images are taken from the same part of the sky at different times
12
12
2º Two stars are identified in both images3º The asteroid can easily be seen by processing the two images (next slide)

Pedagogic Goals
• Authentic Activities– Imitation of real professional's work– System provides scaffolding
• Collaboration is not artificially imposed• Challenge based learning
![Page 14: COLDEX WP 4 Astronomic Scenarios](https://reader036.vdocuments.site/reader036/viewer/2022062304/568132bd550346895d997d9d/html5/thumbnails/14.jpg)

Learning Sceanrio 4: Asteroids
• Astronomy clubs at schools• Challenge: discover new asteroids• They propose an observation program which is
delivered to the telescope operators in an appropiate language and format
• Photographs are taken by the staff and provided to the students. They are also stored in a public repository (following LOR structures)
• Students process the data with appropiate tools• They publish their results in a repository
![Page 15: COLDEX WP 4 Astronomic Scenarios](https://reader036.vdocuments.site/reader036/viewer/2022062304/568132bd550346895d997d9d/html5/thumbnails/15.jpg)

Learning Sceanrio 5: Sunspots
• Challenge: analyse the behaviour and size of the sunspots
• The telescope operators takes photographs of the sun every 3-4 days
• Photographs are stored in a repository from which students can download them
• They measure and describe their movement, again publishing their results in a repository
• They can use hystorical material stored in the repository
• They may use the repository material for other tasks

Value Added
• We propose an integrated view of astronomical observation processed in a collaborative way
• There is no requirement of full remote, nor exclusive operation of the telescope
• Allows sharing of the data generated among all groups• Provides a structure for storing data generated, which will
facilitate its later retrieval and use in different learning scenarios• Provides an interoperative formal language to specify observation
requirements that is simple enough for non-professionals but requires the understanding of some astronomical concepts
• Provides tools for – establishing and processing the required workflow – Processing images– Gaining access to relevant data
