Condition :   Good   
Principle :   Plasma Physics  
Area of Study :  Solar and Galactic Astronomy  
Equipment :   Video: Lightening Whistlers recorded by the P.D.P. (Plasma Diagnostics Package).

  
Procedure :   The P.D.P. was built at the U of Iowa and was used to measure plasmas around the orbiting space shuttle. While in orbit the shuttle and P.D.P. flew over a thunderstorm that was taking place on the earth's surface and 'Whistlers' were recorded. I have copies of this in my video library but there is also a copy with the video machine that is on 3rd or 5th floor. (Spacecraft Engineering)
