From: TerryMosel@aol.com Date: Sat, 1 Jun 2002 18:58:19 EDT Subject: Jupiter, Venus, ISS, & Solar Day Hi all, The last of the spectacular planetary conjunctions this spring is almost upon us, when Venus & Jupiter, the two brightest planets at present, meet in the Western / Northwestern sky. Closest approach is on 3 June; after that Jupiter sinks rapidly into the summer evening twilight, and won't be readily visible until autumn mornings. One final pairing will be the slender crescent Moon and Venus on 13 June: at 11 pm (BST) the Moon will be just 40 arcminutes North of Venus - both visible in the same telescopic view with a wide-field eyepiece in most telescopes. The ISS is still making spectacular bright passes in the late evenings and early mornings. In fact, as the Sun is rarely too low below the horizon to illuminate it, it can be seen at almost any time of night. The launch of the Shuttle Endeavour has been postponed again, until Tuesday, but if it launches then we may still get a chance to see it close to the ISS as they rendezvous for docking. Watch the news for launch details. The first of two special IAA 'Solar Days' will be held as before at the WWT, Castle Espie, near Comber Co Down, at 2.0 - 4.30 on Sunday 9 June. (The second will be at Carnfunnock Country Park, near Larne, Co Antrim, on Saturday 15 June: more details later.) We'll have a variety of telescopes for viewing the Sun, both by projection and through special solar filters to show the view in visible light, and also a special Coronado telescope to show the view in H-Alpha light, so you can see prominences etc. We'll also have Julie Thompson with her renowned show in Armagh Planetarium's portable dome, so there will be something even if it's cloudy. But we have a 100% observing record at this event so far, so here's hoping! Bring any telescopes you have, BUT ONLY if you have a proper filter, or a projection system, for observing. NEVER, NEVER attempt to look at the sun through any sort of optical instrument without special solar filters! Admission is free for IAA members, so come along for a good day's observing & fun. Hope to see lots of you there. Terry
