Uranus is at opposition on 19th October (at magnitude 5.7) in Pisces. The planet is now 1.8° W and slightly N of the mag 4.3 star Omicron Piscium. By the way, the 11.5 mag asteroid 24 Themis lies 27' N of Uranus at 0 h on the 20th October.
Under a very dark, clear, steady skies might some reader glimpse Uranus with the naked-eye?

With the Orionid Meteors at maximum on 21-22 Oct 2017, they are well on view in moonless skies. They are best seen in the small hours before dawn these mornings. The radiant of these fast meteors is in NE Orion. The peak ZHR is 25 meteors per hour (note that this translates to a smaller number even at the peak).

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.
