Example text

A transmitter beamed directly overhead emits a signal that sweeps toward higher frequencies with time. The signal is reflected down again to an adjacent receiver that records the reflected signal a t each frequency along with the delay time from the t,ransmitted signal. This delay time is pro- 50 R. Q. ATHAY AND C. S. WARWICK portional to the “virtual height” of reflection, which is the quantity appearing on the vertical scale of the ionogram. On the ionogram one sees a curve that shows flat portions, with sudden increases of virtual height at the critical frequencies of the E, F1, and F2 layers.

S. WARWICK ment of the emission from ions with high ionization potential and the widening of the line profile both suggest higher temperatures in these active regions than in normal coronal regions. The increased density and emission diminish in both the outward radial and tangential directions, and in a rough sort of way the coronal region can be visualized as a localized condensation of increased density and temperature in the lower corona. Indications are that the temperature may reach 3-5 X 1Oe0K.

The intensity of the second harmonic may be as great as that of the fundamental, but no sure case of a third harmonic has been observed. The type IV event is particularly important in solar-terrestrial relations, as it shows a strong association with solar corpuscular radiation, evidenced by polar cap absorption (PCA) events. First recognized on interferometer records, these long-lived emissions come from a source of large extent that moves in the solar corona to heights of the order of a solar radius [45].
