2 May. Look for Venus in the eastern sky about an hour before sunrise. The planet in early May is preposterously bright, shining at about magnitude -4.7, enough to cast a shadow in very dark conditions. At the beginning of the month, in a telescope, you see about 1/4 of the planet’s face lit by the Sun. By the end of the month, you see the planet half lit as it dims slightly to magnitude -4.5. A truly beautiful ‘Morning Star’.
