The sequence of $(630.0\pm 1)\mathrm{\text{−}}\mathrm{nm}$ images, 16 August 2004, at the Sura facility, Russia. The transmitter-on periods are shown in black on the LT axis. The end of each image corresponds to the end of the exposure time on the LT axis.Reuse & Permissions

Figure 2

Temporal behavior of the maximum of the relative intensity of the $(630.0\pm 1)\mathrm{\text{−}}\mathrm{nm}$ airglow along the cuts through the three airglow clouds shown in the upper right corner during the second cycle of powerful radio-wave transmission. We mark the intensity along the cuts 1, 2, and 3 by gray diamonds, black squares, and gray triangles, respectively. The airglow cloud attributed to the 630.03-nm emission of atomic oxygen appears on top of the cloud 2. The airglow clouds 1 and 3 are believed to be the red emission of OH Meinel rotation-vibrational bands at 629.79 nm. For comparison, the correspondingly scaled photometer data (gray crosses) and the theoretical curve (gray solid line) for the 630.03-nm emission of atomic oxygen for one cycle of powerful radio-wave transmission from Mantas and Carlson [3] are shown.Reuse & Permissions
