Title: Optical aurora observed by all-sky TV camera at Tjornes in Iceland during December 2001.

Organization for this project:
1) National Institute of Polar Research (PI: Prof. Natsuo Sato)
2) Science Institute, University of Iceland (PI: Prof. Thorsteinn Saemundsson)

Observatory name and coordinates:
Name: Tjornes in Iceland
Geographic Coordinates: 66�B11 55��N 17�B05 57��W
Geomagnetic Coordinates: 66.9 S, 73.3

Instrumentation:
High sensitive all-sky TV camera recorded by NTSC digital video recorders (original
data are recorded by 30 frames/sec)

Directions on all-sky TV imagers:
On each TV image, the directions of upward, downward, rightward, and leftward correspond to the magnetic poleward, equatorward, westward, and eastward, respectively.

Data items and data period:
Items: Keograms and movies(sample)
Period: 8 nights from 11 December 2001 to 18 December 2001

Introduction to Keogram:
Keogram shows auroral intensity along the selected line, which is produced from original TV data. The Keograms for Line 1 and 2 represent the North-South directions as shown in Figure (Line 1-2.jpg), and the Keograms for Line 3 and 4 represent the East-West directions as shown in Figure (Line 3-4.jpg). Each Keogram shows one hour time interval at different direction (Line).

Acknowledgments:
Support for the production of S-RAMP Database was provided by grants in aid from the Japan Society for Promotion of Science (JSPS).
