William Henry Harrison. Inaugural Address. President Harrison has the dual distinction among all the Presidents of giving the longest inaugural speech and of serving the shortest term of office. Known to the public as Old Tippecanoe, the former general of the Indian campaigns delivered an hour-and-forty-five-minute speech in a snowstorm.
The Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.Typically, we observe the corona during a total solar eclipse or by using a coronagraph telescope which simulates an eclipse by covering the bright solar disk.he Corona. The outermost layer of the Sun is called the corona or the crown. The corona is very thin and faint and is therefore very difficult to observe from the earth.
The atmosphereâs outer layer is called the corona (crown). In ultraviolet light, it is revealed to be full of loops of hot gas. These coronal loops may rise as high and as wide as 500,000 km (300,000 miles). The inner layer of the Sunâs atmosphere is a pinkish colour and is called the chromosphere (colour-sphere).rom Earth, observers cannot usually see the corona, or outer atmosphere of the Sun, because the photosphere (surface) is so bright. During a total eclipse, however, the moon blocks out the surface and we can see the Sunâs atmosphere.
