Venus and Jupiter closest together on 30th June 2015

venus & jupiter

Venus and Jupiter are a splendid sight, low down in the west, at about 50 minutes after sunset. They are just 22 arcmin apart. Venus is magnitude -4.7 and Jupiter is magnitude -1.8 (i.e. Venus is the brighter of the two).

The two planets will gradually separate in the coming days.

Dr Ian Elliott (1936-2015)

dr ian elliott

The Society is saddened to learn of the passing of Dr Ian Elliott, which occurred on 10th May 2015.

He spent some time at Sacramento Peak Observatory, New Mexico after qualifying as a solar physicist. He was also part of the group site-testing for the solar telescope at La Palma and then was on the Dunsink Observatory staff until 2001, finishing his tenure as Assistant Professor. Ian was co-founder and first Chairman of the Irish Science Centre Awareness Network (ISCAN) and also served as Chair of the Science and Technology Committee of the Royal Dublin Society for some time. He had a deep interest in promoting science and acted as the Irish point of contact for a number of competitions run by the European Space Agency and European Southern Observatory. Ian wrote many articles on the history of Irish astronomy and science, and also had a long-standing interest in the Sun's influence on the Earth's climate. (based on information provided by J.Flannery).

Dr Elliott was also a good friend to the IAS and gave many talks to the Society and wrote a number of articles for Orbit. Our sincere condolences to his wife Dorothy and his family.

Comet Lovejoy 2014 Q2 near Polaris

In late May, the comet passes about 1° from the pole star Polaris. Remarkably, it is still visible (as of 23 May) in binoculars, at just below mag 8. It is an excellent time to image the comet with a fixed camera, as trailing would be slight.

The photo (below) of the comet is by John O'Neill and was taken on 9-10 January 2015 (cropped; 200 mm camera lens). The drawing of 19 January 2015 is by Deirdre Kelleghan, with details appended.

Please report any observations, drawings or photographs to our Director of Observations, Liam Smyth.

Partial Solar Eclipse of 20 March 2015 was visible from Ireland

partial eclipse

Despite a poor weather forecast and the day starting very grey and grim, many saw the eclipse through thin cloud or holes in the cloud.

The photo was taken by J. O'Neill, a little after maximum, through a hole in the clouds (85 mm refractor at 600 mm focal length).

The next partial solar eclipse visible from Ireland occurs in 2017, while for a total solar eclipse, the wait is for 2090!

Members please report any observations, drawings or photographs to our Director of Observations, Liam Smyth by the end of May for inclusion in the July 2015 issue of Orbit.
