Comparable in brightness to the fainter parts of the Milky Way (such as the stretch in Monoceros), the Zodiacal Light is best seen from truly dark locations. From temperate latitudes like those of the British Isles, the best times to look are when the ecliptic is steeply inclined to the evening western horizon (spring) or morning eastern horizon (autumn); the former circumstance applies around the equinox in March. It is also to observers advantage that the distracting glare of both the Moon and Venus will be absent in the western evening sky at this time.The last ten days of March probably offer the best chance to glimpse the Zodiacal Light.
