...newly discovered planet Eros is now the object of special investigation at the Harvard Observatory.

...photographic plate was taken of Eros at Arequipa, Penn, in April and the first of a long series in Cambridge was obtained in July. Owing to its great distance from the earth and consequent faintness a time exposure of two hours and a half was necessary. Plates are now being taken in the early evening, the middle of the night, and the early morning with time exposures of from one to five minutes only.
