As seen from Greenwich the predicted time of disappearance is 2h. 47-Om. U.T. at position angle 38° from the north point of the moon's image; the reappearance is at 3h. 34 om. at position angle 297°. (sunrise is at 4h. 5m.: add 2h. to all times to convert to Midsummer Time). Of the planets visible during this month, Venus is low in the west after sunset and not easily seen. Mars is above the eastern horizon at abeut 23-Jh. in mid-July. The gibbous phase of its disk can be seen in a small telescope. The planet is increasing in brightness.
