The word aurora is derived from the name of the Roman goddess of the dawn, Aurora, who travelled from east to west announcing the coming of the sun. From the bottom, afterglow illuminates the troposphere in orange with silhouettes of clouds, and the stratosphere in white and blue. This forms an obstacle to the flow, diverting it, at an average distance of about 70,000 km (11 Earth radii or Re), [60] producing a bow shock 12,000 km to 15,000 km (1. Diana greatly loved her brother Lucifer, the god of the Sun and of the Moon, the god of Light (Splendor), who was so proud of his beauty, and who for his pride was driven from Paradise.

The earliest depiction of the aurora may have been in Cro-Magnon cave paintings of northern Spain dating to 30,000 BC. An electron spirals (gyrates) about a field line at an angle that is determined by its velocity vectors, parallel and perpendicular, respectively, to the local geomagnetic field vector B.

In addition to all these, a weak glow (often deep red) observed around the two polar cusps, the field lines separating the ones that close through Earth from those that are swept into the tail and close remotely. The rapid decrease of concentration of atomic oxygen below about 100 km is responsible for the abrupt-looking end of the lower edges of the curtains. The strength of the current depends on a) the rate of relative motion, b) the strength of the magnetic field, c) the number of conductors ganged together and d) the distance between the conductor and the magnetic field, while the direction of flow is dependent upon the direction of relative motion. Centuries ago, human settlements were far less concentrated and we lived in far smaller and remoter communities with barely any communication with other tribes. As the women travel together their attraction grows but Aurora is guarding her lonely heart almost as much as her dangerous secrets and Evie is struggling to accept how important Aurora has become to her.

The pitch angle is thereby decreased and increases the chance of it being precipitated into the atmosphere. It is also notable for the fact that it is the first time where the phenomena of auroral activity and electricity were unambiguously linked. Over the night, they begin with glows and progress towards coronas, although they may not reach them. Auroras display dynamic patterns of brilliant lights that appear as curtains, rays, spirals, or dynamic flickers covering the entire sky.It was old, from the time when powerful monsters stalked the night and surviving until dawn was a victory. Early work on the imaging of the auroras was done in 1949 by the University of Saskatchewan using the SCR-270 radar.
