The flare of 12 November 1980, 02:50 UT, in Active Region 2779 (NOAA classification) was studied by using X-ray images obtained with the Hard X-Ray Imaging Spectrometer aboard NASA's Solar Maximum Mission. In a ten-minute period, between about 02:44 and 02:54 UT, some five short-lived impulsive bursts occurred. It was found that the so-called 'hard' bursts (approximately equal to or greater than 15 keV) are also detectable in low energy images. During that 10 min period the impulsive phase - the heat input into the flare and the total number of energetic electrons increased practically exponentially, to reach their maximum values at 02:54 UT. At the end of that period, when the thermal energy content of the flare was largest, a burst was observed, for the first time, to spread in a broad southern direction from an initially small area with a speed of about 50 km/s. This phenomenon has been called a coronal explosion.
