From: TerryMosel@aol.com Date: Sat, 15 Feb 2003 16:38:00 EST Subject: NEAT in a.m., Aurora, Lecture Hi all, It might JUST be possible to see Comet NEAT tomorrow (Sunday) morning, just before Sunrise and maybe on Monday morning too. But only if it is REALLY bright! At 07.00 on Sunday morning (16th) it is 8 deg 26' from the Sun, rising almost directly above it (P.A. 345 deg). From Glengormley the comet's altitude is only 1 deg 17' at 07.00, increasing to 2 deg 36' at 07.10. But sunrise is at 07.44, so the sky will be getting very bright at that time. The further West you are, the later both comet-rise and sunrise will be: add 4 mts for every degree you are West of Belfast (which is approx 6 deg W). And the further South you are, the earlier the risings, although by a lesser amount. It will be 45 degrees Left of, and very slightly below, Venus, at that time. Or if you can see Altair, it will be 32 degrees below left of it, at a 45 deg angle. You'll need binocs or a telescope with your widest-field eyepiece, but be VERY careful not to be observing near sunrise - for obvious reasons! - i.e potential blindnesss if you get the Sun in the field of your binocs or telescope! On Monday morning the separation will be only 6 deg 35', so your chances then are even lower. On Monday morning the comet will be above and slightly right of the rising Sun. But again, be VERY careful not to sweep up the Sun by mistake. AURORA: There's a low-level aurora alert for tonight, but with the bright Moon we'll be lucky to see anything anyway, unless it's a major display. LECTURE VENUE: Some of you were asking about the venue for my lecture "Aliens, Where Are They?" to the Irish Astronomical Society in Dublin on Monday evening. Ely House is at 8 Ely Place, Dublin 2, which is just off Merrion Row. It runs parallel to St Stephen's Green East. Time 8.0. Good luck, Terry Moseley
