"Back into Northern Lights season" - what Yorkshire coast stargazers can look out for in September 2025
Hello and welcome to another monthly Astro Dog Night Sky guide that will help you learn about what there is to see in the night sky.
In this edition of our Night Sky Guide we will be going over what to look out for during the month of September 2025.
September hosts the autumn equinox, the date in our yearly calendar that marks the end of astronomical summer and the start of astronomical autumn.
Just like August, throughout September our nights are rapidly become longer and darker, which is great for those of us who enjoy gazing at the night sky.
Although the Noctilucent Clouds season has now ended, we are now truly within the Northern Lights season, the ringed planet Saturn reaches opposition and is at its easiest to see this month, plus there’s also an amazing total lunar eclipse to enjoy!
And so there is plenty of special celestial event to look out for.
