Solar Day @ WWT, Mayo DSF, Mars, Zoom into MW, Inspiring Stars, INAM, Schrodinger, Arch. Ireland

Hi all,
 
1.  IAA Solar Day at WWT, Castle Espie, near Comber; 18 August, 2.0 p.m. – 5 p.m.. The IAA will be back again at one of our favourite venues for our summer Solar Day on Saturday 18 August. We'll have solar observing if clear, using a variety of special safe solar observing equipment, an exhibition of telescopes, meteorites and other astronomical items, and of course the very popular shows in our own stardome. These shows need to be booked in advance with the WWT – see wwt.org.uk, or email karl.simmonds@wwt.org.uk , tel 02891 875975
 
2.  "The Heritage of the Night Sky". A special event for Heritage Week in Westport on Saturday 18th August at 12noon. Derek Dempsey, Chairman of Newport Astronomy Club, will be unlocking the night sky on the Silver Screen in Westport Cinema. With the help of an open source software called Stellarium, Derek will show you how to identify the starry constellations over a familiar Mayo landscape.  
In addition during this event;
* Festival Director, Fiona Hopkins, will launch our fantastic NEW programme for Mayo Dark Sky Festival 2-4 November
* We will feature a short film by Mayo Dark Skies on protecting the Night Sky. 
* We will have news on how you can get involved in an exciting community project on Mayo's Night Sky Heritage (This project has been funded by the Heritage Council). 
This is a free event - All welcome but please RSVP by email to mayodarksky@gmail.com
   The Heritage of the Night Sky 12noon - Saturday 18th August 2018, W Cinema, James Street, Westport
 
3. Mars.  Reached its best opposition since 2003 on July 27, when it was only 0.3862 Astronomical Units (AU) from Earth.  However closest approach actually occurred on July 31 at 07h 49m, when the separation was 0.3849629 AU from the centre of the Earth. An AU is 149,597,871km, so you (or your Smartphone) can do the maths!
   It reached mag -2.8 (even brighter than Jupiter at its best!), with an apparent diameter of 24.31", and is still bright and appears quite large in a telescope. Since it's now past opposition, it culminates, or reaches its highest altitude on the Southern meridian, a little bit earlier each night, making for slightly more convenient observing.
  Unfortunately it is still very far South, in Capricornus, with a declination of over 26º South, so it's very poorly placed for observation from Ireland. The reason it's so far South is that it's near the most southerly part of the ecliptic, and it actually lies almost 6.5 degrees S of the ecliptic at present!
  The South Pole is tilted towards us by about 9.5 degrees, and as it's Spring in the S Hemisphere of Mars, the S. Polar cap will be gradually shrinking: watch to the end of August to see it decrease in size.
   The giant dust storm that surrounded the planet is slowly clearing.
 
4. MARS's record close approaches: There was a lot of confusion about the 'record' aspect of that approach, with one well known Dublin guy claiming that it hadn't been this close for 32 years! Of course that was nonsense, as the record-breaking close approach in 2003 was the closest for almost 60,000 years!
   And then there were claims that it wouldn't come as close as this again for more than 200 years – More nonsense! It will be closer than this one in 2035, closer still in 2050, and even closer in 2082!
For future reference, here are the actual dates and distances in Astronomical Units
2003, Aug 27: 0.3727 AU
2018, Jul 31: 0.3850 AU
2035, Sep 11: 0.3804 AU
2050, Aug 15: 0.3741 AU
2082, Aug 30: 0.3736 AU
 
5. Amazing Video: Zoom into the centre of the Milky Way, see the stars orbiting the supermassive Black Hole there, and then see their orbits in 3-D.
 
6. Inspiring Stars—the IAU Inclusive World Exhibition, 20-31 August 2018
"Inspiring Stars" will be an itinerant international exhibition promoted by the International Astronomical Union (IAU) to disseminate world efforts on inclusive research and outreach activities in astronomy. This inclusive world exhibition by showcasing assistive research tools and best inclusive outreach practices intends to broaden the horizons of children, parents, teachers and astronomers—everybody can become a scientist (astronomer)—inspiring the love for science in young people's minds. 
   The exhibition will premiere during the IAU General Assembly 2018 in Vienna, from 20–31 August and will be shown around the world. Stay tuned as we keep you posted on all the progress of this IAU not-to-be-missed project for 2018!

Perseids & BBQ, Mars, SkelligsSP, SolarDay at WWT, Events

Hi all,
 
1. IAA Perseid BBQ and Observing Evening, 11 August, Delamont Country Park, Killyleagh, Co Down.
   The Perseid meteor shower is already underway, with rates slowly rising towards the peak expected to occur over the period 11-13 August. These swift meteors, from parent comet 109P/Swift-Tuttle, appear to come from a point in Perseus quite close to the famous Double Cluster, right in the Milky Way. Conditions are very good this year, with no interference from moonlight, so if the sky is clear we can expect a really good display – the ZHR might be around 80, which means that under normal good conditions, after total dark adaptation, we might see 50-60 per hour when the radiant is high up in the early hours of the morning.
   The IAA will mark the event, weather permitting, with a BBQ followed by meteor observing, at our usual observing venue at Delamont, which is South of Killyleagh on the road to Downpatrick.
   The format is that we provide the cooking facilities and utensils, and everyone brings their own consumables, cutlery, plates, drinking vessels etc.
   There are picnic tables so you don't need to bring any tables or chairs. But do bring a lounger or recliner chair for comfortable observing. And warm clothes!
   Obviously if the weather forecast is very bad, we will have to cancel the event at Delamont – check the IAA website that afternoon to get an update on whether it will be going ahead or not: www.irishastro.org .
  If you are observing elsewhere, pick the darkest location available, allow time for your eyes to dark-adapt, and simply look at the sky in the darkest and/or clearest region, preferably about 50 degrees above the hortizon, and in a direction about 40-50 degree either side of the radiant. Instinctively you may want to look at the radiant, but actually you will see more meteors by following the guide above!
   For imaging, again it's best to follow those guidelines, and use the widest angle lens, and highest ISO sensitivity, available. Exposures will depend on sky brightness, so stop each exposure when the background sky starts to get noticeably above normal darkness for a night-time exposure.
 
2. Mars.  Reached its best opposition since 2003 on July 27, when it was only 0.3862 Astronomical Units (AU) from Earth.  However closest approach actually occurred on July 31 at 07h 49m, when the separation was 0.3849629 AU from the centre of the Earth. An AU is 149,597,871km, so you (or your Smartphone) can do the maths!
   It reached mag -2.8 (even brighter than Jupiter at its best!), with an apparent diameter of 24.31", and is still bright and quite large in apparent diameter in a telescope. Since it is now past opposition, it will be culminating, or reaching its highest altitude on the Southern meridian, a little bit earlier each night, making for slightly more convenient observing.
  Unfortunately it is still very far South, in Capricornus, with a declination of almost 26º South, so it will be very poorly placed for observation from Ireland. The South Pole will be tilted towards us by about 10.6 degrees, and as it's Spring in the S Hemisphere of Mars, the S. Polar cap will be gradually shrinking: watch to the end of August to see it decrease in size.
   The giant dust storm that surrounded the planet is showing signs that it may slowly be clearing.
