Hi all,

 

1.  IAA SOLAR DAY at CARNFUNNOCK COUNTRY PARK, Saturday 16 June, 2 p.m. - 5 p.m. The Irish Astronomical Association will be running another of its ever-popular 'Solar Days' at Carnfunnock Country Park, Drains Bay, near Larne, Co Antrim. It's on the main A2 Coast Road, going North from Larne, and is signposted once you are through Drains Bay.

    Now that Solar activity is steadily increasing (there were two big spots today), we can expect to see lots of detail on the Sun's disk if there's any clear sky. We will have a selection of solar telescopes, each fitted with specialised safe astronomical filters, to see it in visible light, and in the wavelengths of Calcium and H-Alpha. There should be sunspots and huge prominences, each many times bigger than planet Earth. We will also have the usual display of astronomical and space items, posters, etc, starshows in the mobile planetarium, and our local 'Ulsternaut' Derek Heatly, so come along even if it's cloudy. I will also lead a tour of the excellent collection of Sundials in the park. 

  We will finish the afternoon with our midsummer BBQ, using the on-site picnic tables at the car park. The usual rules apply - bring along your own food, drinks, eating utensils, plates etc. And ALSO, bring along your own portable BBQ if you have one, although we should be able to provide cooking facilities for those who don't have one. More details on www.irishastro.org 


2. The TRANSIT OF VENUS, 6 June: It seems that most of the island of Ireland was cloudy at the critical time: I know of only two sightings, through breaks in cloud, one in Cork, and one in Wexford. The former was visual only; I believe that a photo on film (remember that?) was taken. The luck of the draw. But we have two Transits of Mercury to look forward to, on

 

3. ISS. The ISS continues its series of evening passes over Ireland. Details are on the excellent free site www.heavens-above.com  

 

4. NOCTILUCENT CLOUDS: We are now into the season when these beautiful high altitude 'night-shining' clouds can be seen lowish on the N horizon near local midnight. They can be seen only when the Sun is at a certain distance BELOW the horizon, when all other normal tropospheric clouds could not be illuminated. They appear a silvery blue in colour, and are thought to be due to high altitude dust from meteors. You often see them near Capella, twinkling in the summer twilight. Send any photos if you capture them.

6. Dunsink Solarfest, 23 June. Following on from the success over the last 3 years, IFAS in conjunction with Dublin Institute for Advanced Studies (DIAS) www.dias.ie and Trinity College Dublin www.tcd.ie are organising a one-day event in Dublin to celebrate solar astronomy. Solarfest 2012 will take place on Saturday 23rd June at Dunsink Observatory, Castleknock, Dublin. IFAS are very grateful to DIAS and TCD for supporting the event and entry is FREE.

   The programme for the event has been finalised: see http://www.irishastronomy.org/index.php?option=com_kunena&func=view&catid=11&id=93657&Itemid=40#93940

 or the IFAS website www.irishastronomy.org.

The event will feature a number of lectures, a workshop, solar observing (weather permitting) and more. The lunchtime break will allow an opportunity to take in a tour of the facility to see the observatory and the 12" Grubb refractor. Tea/coffee will be provided, however please bring your own lunch.

  Spaces are limited to 60 seats. If you are interested in attending, please send an e-mail to ifas.solarfestat signgmail.com. Please state in the e-mail how many seats you would like to reserve.

  Regards & Thanks, Michael O'Connell

(NB: Dunsink Observatory is on Dunsink Lane, Castleknock, Dublin. The Observatory is at 53 deg 23' 14.3"N, 6 deg 20' 19.0" W, with the entrance off Dunsink Lane at 23' 16.6"N; 20' 14" W. But Dunsink Lane has been blocked on the city side, and the observatory is now only accessible from the New River Road end, off the Navan Road, near the junction of the N3 and the M50 - the Castleknock junction, Junction 6. Since the M50 upgrade this has become a very complex junction.

    If approaching via the M50 from the Dublin airport direction, you MUST get into the correct lane at the offslip, or you'll be way off course! So when you approach Junction 6, move onto the offslip lane (to the left, obviously), but then stay on the two right hand lanes of the offslip, signed for 'Castleknock'. Do NOT keep on going round to your left via the left hand lane on the offslip, which will take you on to the N3 and Castleknock village! (That seems wrong when you know where Dunsink is, but believe me - I learned the hard way! If your Satnav says something else, ignore it.)

    Then move into the left hand of the two 'right' offslip lanes (in other words, the middle one of the three). This will bring you to the original roundabout, with traffic lights, where you then keep left, and then immediately left again, signed for 'Dunsink'.

   This road leads directly on to New River Road. At the 'cul-de-sac' sign continue on straight, and it becomes Dunsink Lane. Go straight on for almost 2 km (past Elmgreen Golf Course) until you see the road blocked ahead of you: the entrance to the Observatory is on the right just before the block. 

   If you go this way, it's simple and easy, so don't be put off - just follow those directions exactly.

On the return journey you go back along Dunsink Lane, then follow signs for the M50 Northbound. (TM)
