Deceleration observed in the coronal mass ejection event of July 25, 1999

We present height-time diagrams of the halo coronal mass ejection observed on July 25th (1999) from the Large Angle and Spectroscopic Coronagraph (LASCO), on board of the Solar and Heliopheric Observatory (SOHO) able to observe the solar corona from 2 to 32 solar radii. We used a technique in which...
