Scientific paper

The EIT, LASCO and UVCS instruments aboard SOHO observed a CME on Dec. 11/12 1997. The ejected prominence material rose relatively slowly, averaging 150 km/s, but Doppler shifts as great at -300 km/s were seen in the O VI lines. The observed gas spans the temperature range from about 30,000 K to 300,000 K. The observations can be modeled as left-handed helix which untwists at about 0.0009 radians/sec. Considerable heating as the plasma moves from the solar surface to 1.7 solar radii is required to explain the observed temperature range.
