At the Dominion Observatory, Kelburn, in January and February last, as part of a world-wide campaign, a series of photographs of the minor planet Eros was taken, the planet then being closer than usual to the earth. How this photogranhic work was carried out was described at the last meeting of the Astronomical Section of the Wellington Philosophical Society, Messrs. I. .L. Thomsen and F. M. Bateson reporting on the work. It was apparently a more difficult task than anticipated to find the planet at all. Plates were exposed on the region of the sky where Eros was calculated to be, and when these were developed and superimposed it was found that one little object in the sky had moved its position in relation to the surrounding stars. This turned out to be Eros. Photographs were taken when possible on succeeding days, and the best of them were those taken last bn February 15. On that date they did not allow Eros to make its “trail” on the plates, but took several short exposures at not too distant intervals of time. The result was that they got fairly intense star, images together with point images of Eros in slightly different positions. These point images were satisfactorily measurable.
Just at present there are special lines to be picked up at a reduced price, which means four pounds will go further when these lines are wanted lines. It means a further saving. See McGruer's, Central Devon Street, advertisement, then act.
