Papers of John Guy Porter

A copy of Porter's script for 'The Night Sky in February' on Venus and Jupiter in the evening sky, with Jupiter at opposition near Regulus and Venus in the south-west; the difficulty of observing Venus because of its brilliance and cloud cover; the streaks in the clouds seen by observers and the work of Gerard Kuiper on the cloud belts of Venus at the McDonald Observatory; Leo, the Plough, Acturus in Bootes, Corona Borealis and representations given this asterism; Vega and Altair in the aspect of eagles; spiral galaxies near Corona Borealis in clusters, the double stars in the neighbourhood, and R. Coronae Borealis, its variability and the possibility that there is solid carbon in its atmosphere; and T. Coronae Borealis - the 'blaze star' of 1866, a nova not near the Milky Way, which reappeared in 1946.
