The Planets - August 2022


Given a very low western horizon Mercury might be observed after sunset during the first few days of the month just north of West when it will have a magnitude of -0.55 and an angular size of 5.3 arc seconds.


Venus can be seen very low in the East-Northeast in the pre-dawn sky at the start of the month having a magnitude of -3.84. As dawn becomes later during the month, it is still just visible before dawn by month's end when its brightness will have increased a little to -3.87.


Mars rises at 1am (BST) at the start of the month and can be seen down to the left of Jupiter in the east-southeast before dawn. Under good seeing conditions, some details on the surface might be seen, particularly by the end of the month when its elevation will reach 47 degrees before dawn.


Jupiter rises at 11pm (BST) at the start of the month and dominates the pre-dawn sky in the Southeast. By the end of the month its magnitude will have increased a little to -2.86 and its angular size to 48.66 arc seconds as it moves towards opposition on the 26th of September.


Saturn rises in the southeast at 10pm (BST) and reaches an elevation of just just 23 degrees as it then transits at 2am (BST). Sadly its low elevation will hinder our view of this most beautiful planet for some years to come.
