Abstract
OCCULTATION OF A STAR BY SATURN.—Mr. A. Burnet has pointed out that the star Lalande 20654 (mag. 7.3) will be occulted by Saturn on the evening of March 14. Mr. L. J. Comrie gives some further details and a diagram in the Journal of the British Astronomical Asso ciation for January. At Greenwich the star disappears at 7h. 5m. in position angle 281°, just to the north of the ring, reappearing at 8h. 40m. in angle 121°. The star will pass very close to Titan about 12h. 15m., and an occultation by that satellite will probably occur somewhere on the earth; hence it is important to observe the conjunction with care, and, if an occultation occurs, to take the times of disappearance and reappearance, as a useful determination of Titan's diameter might be made from such observations. A central occultation would last about five minutes.
