24 hours, right? It had most definitely been a whole day, possibly more, on account of Alice had gotten lazy and forgotten to pick her telescope up. To be honest, it could have been cleaned a month ago and she wouldn't have realized. But when it finally occurred to her that she had to start working on Aireyhead's assignment sometime, the sixth year had grudgingly made her way to the laboratory again.

... which one was hers?

It took quite a while for her to locate the telescope that she thought she'd cleaned, though Alice was only judging by the fact that it looked shinier than any of the others. Did it really matter, though? She had stargazing to do and such. This one. Hers now.
