ABSTRACT THE COMET GRIGG-SKJELLERUP.—Mr. G. Merton read a paper on this comet at the meeting of the Royal Astronomical Society on December 10. The identity of the comet found by Skjellerup


in 1922 with that found by Grigg in 1902 was first suggested by Crawford and Meyer. Mr. Merton has made it a practical certainty. He gets practically the same mean motion in 1922 from the


observations in that year alone (they extended over three months, so the value is trustworthy) as by combination with those of 1902. The comet is due to return to perihelion on May 10, 1927;


Mr. Knox Shaw is now searching for it with the large reflector at Helwan. It may be expected to be found not later than February. It approaches within 17, million miles of the earth in


June; Comet Pons-Winnecke makes a still nearer approach (some 4 million miles) near the end of June. Access through your institution Buy or subscribe This is a preview of subscription
