Direct Observation of Temperature Amplitude of Solar 300-SECOND Oscillations
Abstract
The 300-second oscillations form the dominant source of variability of the solar infrared continuum. We have observed them at 20 with an amplitude AT, = 3.0 K over an area with an effective diameter of 33". This new mode of observation of the 300-s oscillations should make possible a fundamental improvement in our knowledge of their nature and origin. Subject headings: Infrared solar atmospheric motions
