Hi all,ƒŠ

ƒŠ

1. SOLSTICE INTERVIEW:ƒŠ- Apologies to the few of you who were disappointed that my Solstice interview did not broadcast -ƒŠitƒŠwasƒŠedged out by a certain Graham McDowell winning the US Open!

ƒŠ

2. COMET: Comet McNaught 2009 R1 continues to brighten slowly, but is very difficult to find in the bright all-night summer twilight. On the morning of the 22nd it was about mag 5.8, but not visible even in 10x50 binocs because of the bright background sky. Even in 30x80s and 25x100s it was unimpressive. Those further south in the island will have a darker sky background, but the comet will also be lower down in the N sky when twilight is at a minimum. It is expected to be brightest on July 1, but will then be even closer to the Sun. Try for it now if you want to see it at all. See: http://www.aerith.net/comet/catalog/2009R1/2009R1.html

3. NLCs: There have been some sightings, so keep a look out in the NNW sky as soon as it gets dark enough to see Capella in that region of the sky. Send any photos to the IAA website: www.irishastro.org

4. RARE BRIGHT OCCULTATIONƒŠ- for those on holiday in Europe! On the evening ofƒŠJuly 8 there will be an occultation of the bright star Delta Oph (mag 2.7)ƒŠby asteroidƒŠ472 Roma. The asteroid itself will only be visible in large telescopes, but as it will pass between us and the star, the star will suddenly disappear for a few seconds, and this will be visible evenƒŠto the naked eye!

ƒŠƒŠ The occultation will occur around 21:57 U.T. (22.57 BST, but allow for local time in whatever country you are in, i.e.ƒŠconvert from UT, whichƒŠequals GMT. The expected maximum duration of the occultation is 5.6 seconds.

ƒŠ ƒŠThe narrowishƒŠtrack of the occultation (like a 'mini-eclipse') runs from SƒŠPortugal (Algarve region)ƒŠacross NE Spain, France, the Low Countries, N Germany, S Sweden and Finland. If you happen to be on holidayƒŠanywhere near the trackƒŠon July 8, do have a look for this extremely rare event.

ƒŠƒŠƒŠ See: http://www.astrosurf.com/eaon/phenomenon%20rare.htm. The darker central track is the expected path where the occultation will be visible: the closer you are to the centre, the longer the duration of the occultation. The shaded area on either side is the zone of 1-Sigma uncertainty: in other words if there is an error in either the position of the star or the path of the asteroid it's possible that the occultation could be visible in this zone. If there's an update on the track before the event it will be posted on that website.
