This suggests that the sun is not a rigid body and thus understand the resulting solar activity.
This activity aims to evaluate the angular velocity of sunspots from the video, made by spectroheliograms April 2013, provided by the Astronomical Observatory of the University of Coimbra, demonstrating the sphericity of the sun as well as their behavior as body fluid, using the effect of the Tracker (free software used in digital video analysis)">"Solar rotation"; "sun angular velocity"; "sun sphericity"; "sunspots motion"LOM v1.0final1.0LOM v1.0author2013-05-15Alvaro FolhasLOM v1.0publisherenLOM v1.0LOM v1.0creator2013-05-15Alvaro FolhasLOM v1.0validatorLOM v1.0LOM v1.0LOM v1.0osLOM v1.0ms-windows7text/htmlhttp://portal.discoverthecosmos.eu/node/194950LOM v1.0noLOM v1.0noLOM v1.0mixedLOM v1.0mediumLOM v1.0mediumLOM v1.0Inquiry-Based TeachingLOM v1.02 didactic hours15-18LOM v1.0DisciplineScienceAstronomy: Solar activityAstronomy: Sunspots
