Fergie wasn't really a big fan of Astronomy, to be quite honest. Professor Trishna was nice, which was a plus when compared to some of the others (the Durmstrang League, for example). But the muggle stuff made his head ache, and he really just preferred to have his evenings free.
At least, apparently, the lecture portion would be shorter tonight. Fergie didn't mind lectures, usually, but Astronomy took place not too long before his usual bedtime. The longer the lecture lasted the more likely he was to zone out and start drifting off to sleep. Star charting would at least give him something to focus on and stay awake for, even if he was only interested in it due to how it related to Astrology and Divination. And while the weather was, as Professor Trishna had said, improving, it was still chilly enough out to keep one awake.
Settling into his usual seat, towards the back of the room, Fergie produced his note taking supplies and arranged them neatly on the desk in front of him, and gazed out the enchanted windows (those were at least always interesting) while he waited for the lecture to begin.
