Fri 10th - Sat 11th February 2017.
Normally Penumbral Eclipses are hard to discern. However, at this eclipse virtually all of the moon will be immersed in the penumbral (or semi) shadow of the Earth. The eclipse begins at 22:34 UT and ends at 02:53 UT (Irish Winter Time is the same as UT). The slight dimming of the moon's northern hemisphere should be most noticeable around mid-eclipse at 00:44.

Angela O'Connell reports:
A view of totality from the MS Volendam, on the starboard bow, mid-ship. We were located in the Makassar Strait between the islands of Borneo and Sulawesi, about 1½ degrees south of the equator. The sea was surprisingly calm and the ship was steady allowing those of us with tripods to relax and concentrate on the spectacle which lasted 2 min 46 sec approximately. Photo (at left) taken 08:34 (local time), 9th March 2016 with Lumix GM5 on automatic night scene setting.
Terry Moseley reports:
The solar corona during totality. Photo taken 08:36 (local time), 9th March 2016 with Canon Power Shot with x42 zoom.The next total solar eclipse occurs in August 2017, only touching land in USA.
We were treated to a fine total lunar eclipse.
The photo of the eclipse was taken by J. O'Neill, at 02.21 UT, with a 106 mm refractor at f/8. This was 10 min after the start of totality.
The next total lunar eclipse visible from Ireland occurs in July 2018.
Members please report any observations, drawings or photographs to our Director of Observations, Liam Smyth for inclusion in the next issue of Orbit.
In late May 2015, the comet passed about 1° from the pole star Polaris. Remarkably, it was still visible (as of 23 May) in binoculars, at just below mag 8. It was 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.
