7. Sep 18: International Observe the Moon night - The IAA hopes to run an observing session just outside Holywood, Co Down. Other clubs may be doing something similar. See

8. Mercury will at greatest western elongation on Sep 19 and will be visible as a 'morning star' in the east during the second half of the month. Look about 45 minutes before local sunrise, slightly to the South of where the brightest part of the dawn twilight appears. On the 19th it is mag -0.3; it then brightens as it moves towards Superior Conjunction and therefore shows more of its illuminated disc towards Earth, and by Sep 30 it is mag -1.1.

9. Jupiter will be at opposition on Sep 21 and is well placed for observation all this month. It now rises in the evening twilight and by month’s end it will rise just before sunset. It lies in Pisces, at mag -2.9. It is also at conjunction with Uranus on the 18th; much fainter Uranus will lie less than a degree to the North of Jupiter. Jupiter’s South Equatorial Belt is still 'missing'. The four Galilean moons are visible in a small telescope or good binoculars.

Clear skies,

Terry Moseley
