1. IAA Public Lecture Meeting, Wed 1 March: "Building bridges to the mysteries of our Universe with the brightest cosmic explosions ", by Dr Cosimo Inserra, QUB
SYNOPSIS: We know only 4 per cent of the Universe, the other 96 per cent is made of things that astronomers cannot detect or even comprehend. Supernovae are stellar explosions capable to outshine the luminosity of an entire galaxy. It means that a single star explosion can radiate more energy than 100 billion stars altogether. It is thanks to such explosions that we can have heavy elements like iron on our planet, as well as the Earth itself. Furthermore, it is exciting how Supernovae can also help us to understand the aforementioned missing and mysterious 96 per cent of our Universe, something that astronomers call dark energy and dark matter. Thanks to their luminosity they can be seen up to very far distances and since the speed of light, although incredibly fast, is limited looking at very distant Supernovae we can retrieve information about the past of our Universe. Such information can tell us more about how was our Universe and how it is going to evolve in the future. Thanks to this exceptional and unique property, Supernovae can be used as a sort of time machine for information.
One of my most significant research to date focuses on the use of the brightest supernovae, as cosmological probes at high distances. Thanks to their intrinsic brightness, ten times more than those of the Nobel study, we have the possibility to explore our Universe ten times further in space and time. This research will allow us for the first time to observe the behaviour of the dark energy and dark matter at the beginning of the cosmos. It will also give new and unpredicted information on their nature and, hence, also more details about the future of our Universe. Such innovative departure from traditional studies is already breaching the initial skepticism and has been used by several groups to stress the importance of these Supernovae in current and future world-wide cosmological projects such as the Dark Energy Survey, the Large Synoptic Survey Telescope and the European Space Agency (ESA) Euclid mission.
TIME: 7.30 p.m., Bell Lecture Theatre, Physics Building, QUB.

2. Venus, 'The Evening Star' is now plunging into the twilight. Venus is still very prominent in the SW in early evening twilight but is getting much lower in the evening sky as it moves in closer to the Sun as we see it, as it heads towards inferior conjunction on 25 March. However, the angle of the ecliptic to the horizon is still increasing for us in these latitudes, and further, Venus is moving gradually further North of the ecliptic as we see it.
It is now just past peak brightness, at mag -4.4, and completely outshines neighbouring Mars, which lies over a third of the length of the 'Plough', or 'Big Dipper', away to the upper left. Venus's phase is now noticeably decreasing as it moves between Earth and Sun: it's now about 7%, similar to a 1-2 day old Moon.
Here are its elongation from the Sun in degrees; phase; apparent diameter in arcsecs, and magnitude, for the following evenings in March:
11th: 22.0 deg; 7.2%; 54.5"; -4.4
13th: 19.6 deg; 5.7%; 55.7"; -4.3
15th: 17.2 deg; 4.3%; 56.8"; -4.3
17th: 14.7 deg; 3.2%; 57.8"; -4.2
19th: 12.4 deg; 2.2%; 58.5"; -4.2.
In the next bulletin I'll describe how this is a VERY rare chance to follow Venus right through inferior conjunction - something I've never managed to do in over 50 years observing!
3. Heavens Above: AstroPhoto Exhibition, now in Downpatrick.
The superb exhibition of locally taken astro-photographs, which had very successful runs in the Linenhall Library In Belfast, and Clotworthy Arts Centre in Antrim, and the Island Arts Centre in Lisburn has transferred to the St Patrick's centre, Downpatrick, and runs there until 31 March.
Also, there are 5 movies, covering solar eclipse, auroras and conjunctions, playing on a
loop all day and now also viewing in the Centre reception.
Thanks again to Bernie Brown for setting this up.
4. ISS. The International Space Station commenced another series of morning passes over Ireland on 3 March. Details as always on the excellent free site www.heavens-above.com. This site also has general information on most things visible in the night sky, including comets.
5. The International Day of Planetaria (IDP), 12 March: The IDP goal is to involve the international planetarium community in a collaboration that promotes awareness of planetariums to the public. The IDP was first conceived by the Associazione Amici dei Planetari in Italy. In 1995, when other planetariums in Europe joined in the celebration, it became a truly international day. Today it is also celebrated in the United States and Australia and it hopes to continue to grow towards having a global reach.
The International Day of Planetaria (IDP) will be celebrated on 12 March 2017 and all planetariums, regardless of affiliation, are invited to take part. See https://ips-planetarium.site-
7. PhD Studentship in High Energy Solar Physics
8. St Patrick's Day events, Armagh Observatory and Planetarium
Armagh Observatory and Planetarium is hosting two education and public outreach events on St Patrick's Day Friday 17th March.
A. At 11:15 there will be a free public lecture in the Studio Theatre, The Market Place, Armagh: "Discovering Stars, Our Milky Way and Our Place in Space". The lecture, which will be given by Professor Michael G. Burton (Director, Armagh Observatory and Planetarium), is aimed at the general public and all are welcome.
B. There will be a 2-hour afternoon guided tour of Armagh Observatory and its Grounds, Astropark and Human Orrery. An explanation of the Observatory's Sonic Art exhibit "aroundNorth" will also be provided. The tour starts at 2.30pm and will end around 4.30pm. Visitors should note that because much of the tour will be outside, they should wear appropriate clothing in case of cold or inclement weather.
Those who wish to attend the free public lecture in the Market Place Theatre should contact the Box Office on 028-3752-1800 or online at http://www.armagh.co.uk/event/
9. AstroCamp 2017 The European Southern Observatory (ESO) and the Centre for Astrophysics of the University of Porto (CAUP) are collaborating to support AstroCamp 2017, an astronomy-focused summer academic programme for secondary school students. The Summer AstroCamp 2017 will be held from 6 to 20 August in northern Portugal, at the Centre for Environmental Education and Interpretation of the Corno de Bico Protected Landscape. The applicant with the best application from one of ESO's Member States who is eligible to apply will win a bursary offered by ESO that will cover the camp fee.

10. HYPATIA DAY, 20 MARCH: For those of you unfamiliar with this 'universal genius', the world's first known female astronomer, often known as Hypatia of Alexandria, Brittanica.com states: "She was, in her time, the world's leading mathematician and astronomer, the only woman for whom such claim can be made. She was also a popular teacher and lecturer on philosophical topics of a less-specialist nature, attracting many loyal students and large audiences."
The historian Socrates of Constantinople described her in his Ecclesiastical History: "There was a woman at Alexandria named Hypatia, daughter of the philosopher Theon, who made such attainments in literature and science, as to far surpass all the philosophers of her own time. Having succeeded to the school of Plato and Plotinus, she explained the principles of philosophy to her auditors, many of whom came from a distance to receive her instructions. On account of the self-possession and ease of manner which she had acquired in consequence of the cultivation of her mind, she not infrequently appeared in public in the presence of the magistrates. Neither did she feel abashed in going to an assembly of men. For all men on account of her extraordinary dignity and virtue admired her the more."
Currently 20 March is being petitioned as an ideal date to commemorate the first female astronomer — Hypatia of Alexandria. As the petition gains momentum - there are 40 participating countries overall, Uruguay, Colombia, Venezuela, Nicaragua and Chile having recently joined - the organisation is aiming to formalise a proposal to UNESCO so that on Hypatia Day we can globally celebrate Women in Science day.
I would like to see the UK and Ireland both supporting this. You can vote and learn more about the project here http://bit.ly/2kKt1TA

13. Earth Hour, March 25 This annual campaign, to switch off all but essential lights for one hour, from 20:30 to 21:30, is now 10 years old. It has two aims : to save energy, not just for that one hour, but to show that much lighting is not really needed, and to let people see the beauty of the night sky. Turn off and look up at the stars! Make your own starter kit of ideas. Please share your plans and any photos of the night - as more and more individuals turn off for an hour, the night sky comes to life.
