MERCURY is now a morning object, and attains its greatest elongation of 28° W. on March 15. Venus, on the other hand, is moving round to its greatest eastern elongation (45° E. on June 30) and has already become a conspicuous object in the evening sky just after sunset. Mars is well placed for observation, being very nearly in opposition. Jupiter is a morning object, and Saturn is very near the sun. An interesting conjunction of Venus and Uranus will occur on March 22 at 7 hours, when the planets will only be separated by 0·4°. This conjunction will, of course, be invisible in England, but the two planets should be seen close together, in a small telescope, on the evening of March 21 or of March 22. Neptune is well placed for telescopic observation, being in opposition to the sun on March 4.
