alt_sinistraFifth and sixth years: Madam Umbridge will be observing our evening teaching sessions tonight. I’m sure you will give her every possible courtesy. It does look like it may stay clear, so please come prepared to work outside.
Fifth years: we’ll be coming back to locational magic theory in lecture next week (and your observing tonight will relate). If you still have questions about what we’ve covered so far, please have them ready for your next lecture. Or ask here. (Beyond the usual reasons you might want to learn something, yes, it will be on your OWLs.)

You're welcome, though I hope we won't need that skill again soon, even if it does amuse you. And thank you, Tosha, for the invite, but Dolores implied she'd be up here early, and I am not letting her alone in my tower. The excuse to get her to leave may, however, be very handy.
Locational calculation - here? How tightly defined? I've all the tables handy at the moment, since the observing the 5ths are doing uses them, and I can dig out the good sextant. I can guarantee you accuracy to about 200 yards, but could get it a bit tighter than that with a little more work.

Date: 2012-11-29 04:04 am (UTC)Speaking of help, however: do not put yourself to any trouble yet, as I'm not yet positive that my instincts are correct -- I need to check Raz's opinion first, and to make sure what I have in mind is even possible, and I would appreciate your thoughts as well. What I have in mind: there is a spell that will, until it is dispelled, prevent its target from casting any magic at all without permission of the caster. I am checking my references, but I believe it will be possible to modify it so that it will only prevent the individual from casting magic on another, and expand it so any teacher might give permission. The locational magic, meanwhile, is because I had thought to leave it active only at Hogwarts itself, lest parents accuse us of overstepping our boundaries. If it is possible for accuracy that narrow, that is.
It is only a thought. But I believe it is the best way to get the point across.

Date: 2012-11-29 04:13 am (UTC)Haven't we already discussed the fact I enjoy being helpful? My mood is entirely not about you, it is therefore unfair to take it out on you. Either of you.
As to the calculations - look, let me take the initial measurements tonight. I could do a first approximation of the area around Hogwarts from that, easily. If you want something more defined - say, the Hogwarts ground but not Hogsmeade - I'd need to do a few more from other points on the grounds, but I can easily do that once it gets dark tomorrow.
(I spare you the discussion about single point calculation from the sun versus multiple point triangulation using the fixed stars and planets. The latter is far more elegant and precise.)
Hypatia's blood - she is early. I hear her on the stairs now.

Date: 2012-11-29 04:22 am (UTC)A close approximation would suffice, I suppose -- I cannot foresee a reason why Hogsmeade would need to be excluded, and actually, including an area around the castle might be wise, lest they simply sneak out and carry on.
As to Dolores -- courage, my dear. I have faith in your ability to be impeccable in your work.
