This page shows a brief summary of what interesting things we can see in the sky this month.
A more detailed version of the 'What's Up' this month is available as a downloadable PDF document right at the bottom of this page.
September brings about the start of Autumn, arguably the best time for observing, with dark skies by nine and weather that keeps you warm enough for hours of viewing. Highlights for this month include Pleiades and Orion emerging.
The Sun
Remember to never look at the sun with a telescope, at worst you might blind yourself, at best you’ll melt your telescope! If you are interested in Solar viewing, speak to our members, we have special equipment to help you! If you do not have a solar scope, watch using Solar and Heliospheric Observatory (SOHO) or SDO.
The Moon
The phases of the Moon are as follows:
Darkest skies due to lack of moonlight are during the week of 12th to 18th September.
Apogee on the 12th at 226,485 miles, Perigee on 28th at 251,379 miles
Tricky viewing, but best on the 22nd of September at 5:45 am low in the East.
Venus, getting higher each morning, best on the 30th of September, 25 degrees high in the East.
