Increasing Astronomical Darkness

Sunset_Scotland_(5805593910)

You might notice the nights seem to be pulling in quickly at the moment. This isn’t your imagination. We’re in a period of greater daylight change as we approach the Autumn equinox on September 22nd.

At the moment the Sun is setting around 20 mins earlier each week. Compare that to July when Sunset times were only changing by around 5 mins per week, and almost no noticable change over the summer solstice on June 21st.

Of course this is great news for stargazers, with astronomical twilight now kicking in around 9.50pm meaning your late night forays under clear skies will reveal increasing numbers of stars and fainter nebulae.

For seekers of dark skies this month’s new moon is September 9th so binoculars, cameras and telescopes at the ready.

Clear skies.
