Sophie decided to go up to the Observatory to do the night part of her Astronomy homework. It didn't seem 100% safe to be on her own in Hogwarts grounds... well, at least she didn't feel like going out there alone at night. You know... it was pretty dark.

She sat on the floor and pulled the nocturnal out of her bag. After her improvised attempt to tell time using the sundial, Sophie thought it was best to read a little about the nocturnal instead of trying to figure it out all by herself. She had been able to tell time with the sundial because she could tell time by looking at the direction of her shadow, but she wouldn't be able to do that with the stars.

Before reading anything about the object, she decided to observe it and see what could move around and what each disc and... thing could do. It seemed she needed her finger to see; she touched everything and turned the discs and the pointer arm around. She had to admit the whole thing looked really cool!

Hmm... the letters indicated the months of the year! Sophie smiled at the observation. And... plenty of numbers. Where they to indicate the date or the time? Or both?? Gee, this was getting a bit more complicated than the sundial...
