It's #StrawberryMoon day! And before you scoff "but the full moon happens every month Catherine", this is the once-every-18.6-yr lunar standstill. In the Northern hemisphere the moon will rise just above the horizon (look S) before it dips back down again 1/🧵🧪🔭 ⏰ www.timeanddate.com/moon/uk/edin...

There is some lovely celestial dynamics going on. The Moon orbits the Earth once every 27 days, but its path is tilted at an angle of 5° relative to the orbit that the Earth takes around the Sun. This 5° is why we don't see a total solar eclipse for every new moon! 🔭 2/🧵
Our beautiful planet is also tilted as it circles the Sun, which gives us the different seasons. In the Northern hemisphere, the summer solstice is when the Sun is highest in the sky, for the longest time, and that moment is coming soon on the 21st June at 3:41am (UK)🔭 3/🧵 bsky.app/profile/astr...

When we see a full moon it's directly opposite to the Sun. During the summer solstice, the Sun is at its highest in our skies, meaning that the full moon that falls closest to the solstice will appear at its lowest elevation in the sky. 4/🧵🧪🔭 📷: @earthskyscience.bsky.social
The rare lunar standstill happens around the solstice when the moon at its most extreme point in its 5° tilted orbit. This only happens every 18.6 years and the further North you are, the better. #DoLookUp tonight! 🧵/end 🧪🔭 ℹ️: www.skyatnightmagazine.com/news/strawbe...
