Dale comments: NGC 6309, the Box Nebula, is a planetary nebula in the constellation of Ophiuchus. It's a fairly dim target, having a mean surface brightness of only 11.0. I was drawn to observe this after my friend Frank McCabe had observed & sketched it 24hrs before from Chicago. I made this sketch using the 505mm mirror & Watec 120N+ video camera on a barely dark mid summer night 28th June 2012. North is up, East is left. Note the slightly 'Mummy' shape to the nebula, the mottling and dust lanes visible distinctly along the western upper edge. Also some nebulosity can be seen streaming to the east. Hope you findmy observation of thisdistant stellar remnant in our galaxy interesting?

Whilst await the recent Venus solar transit, Alex Pratt in Leeds was able to capture the ISS as it passed across the disc of the Sun, despite a troublesome breeze and variable cloud cover. Imaging details are on the image. The prediction of the circumstances at my location was generated by CalSky.com Best regards, Alex R Pratt (Leeds)

This sad message was received from BAA member John Thorpe in Perth, Western Australia: We are St Hildas Astronomical Society in Mosman Park near Perth in Western Australia. We had hoped to send our pictures of the Transit of Venus. Alas, the Perth weather decided to pick June 6 as a good date to start our winter and we had cloud and rain for the entire duration. All we can offer is a picture which perhaps expresses our frustration, and shows how we had hoped to observe, with our Astroscan telescope and a whiteboard. Best wishes Mr John Thorpe.

This image is a comparison of photographing the same portion of the Milky Way from suburbia (Whitley Bay, Tyneside) and in the country (Rookhope, North Pennines). This is the Cygnus area; the bright star on the right just above centre is Vega. Part of the problem in suburbia is that you cannot take exposures as long as you can in the country without the detector saturating. The photo on the right is a stack of 32second exposures at ISO 6400 but on the left only 10seconds at ISO1600 was possible for each individual exposure.

Unusually large NEO 2012 LZ1

An unusually large Near-Earth Object, 2012 LZ1 has just been discovered by Rob McNaught and colleagues on 2012 June 10/11 using the 0.5-m Uppsala Schmidt telescope at Siding Spring, Australia as reported in MPEC 2012-L30 issued on June 12 09:30 UT.

The newly-discovered NEO is approximately 300-700 metres in size (H=19.7) and makes its closest approach of 0.036 AU (about 14 lunar-distances) on June 15.0 UT.  The object will be visible from the UK near closest approach rather low down in a south-eastly direction and may be best seen before dawn (around 01:00-02:00 UT) on Friday, June 15 as an asteroidal object, magnitude 13.9 or so, moving at an apparent speed of about 38 “/min at an altitude of roughly 25 degrees above the horizon.

BAA Member Martin Mobberley captured these images  using a remote telescope in New Mexico.

NEO 2012 LZ1 imaged by Martin Mobberley on 2012 June 14

NEO 2012 LZ1 imaged by Martin Mobberley on 2012 June 15

 

Unusually too, although moving in an orbit inclined at 26 degrees, its motion is quite commensurate with that of the Earth at the moment and so the object will remain visible from the UK on many successive nights as it moves further northwards.

During the next ten days, the declination, brightness and apparent speed will be as follows:

June 14/15  Decl. -15  V=13.9  38″/min
June 15/16  Decl. +01  V=14.2  36 “/min
June 16/17  Decl. +13  V=14.6  30 “/min
June 17/18  Decl. +23  V=15.1  23 “/min
June 18/19  Decl. +31  V=15.6  18 “/min
June 19/20  Decl. +37  V=16.0  13 “/min
June 20/21  Decl. +42  V=16.4  10 “/min
June 21/22  Decl. +46  V=16.7  8 “/min
June 22/23  Decl. +49  V=17.0  7 “/min

Note that the summer solstice this year occurs on June 20 at 23h UT at which time this object will be visible from the UK in a westerly direction at an altitude of some 54 degrees.

Given its size and proximity to the Earth, 2012 LZ1 is the latest potentially hazardous asteroid (PHA) discovered.
Congratulations to Rob McNaught on this particular find which was conducted as part of the Siding Spring Survey; an NEO search program, the southern hemisphere counterpart of the Catalina Sky survey.
See:  http://www.mso.anu.edu.au/~rmn/

Sky coordinates for finding this new visitor to the Earth’s neighbourhood can be obtained from the Minor Planet Center’s ephemeris service at:
http://minorplanetcenter.net/iau/MPEph/MPEph.html
Remember to enter a suitable Observatory Code in the online form to achieve a satisfactory topocentric prediction.  For the UK, you might wish to use the Code for Greenwich namely ‘000′.

Observers are encouraged to report astrometry to the Minor Planet Center.
Please report photometry to the nearest 0.01 mag to Richard Miles, Director, Asteroids and Remote Planets Section,  British Astronomical Association

This week we have cheated just a little bit with POTW. We are running a montage, with the main feature one of Martin Ratcliffe's Venus transit images from Wichita, Kansas (see the transit page for full details) and as an inset we have just received a videocam image from Dave Eagle of the planet at 1000 BST on 20120610. Well done to both observers, and thanks Dave for checking that Venus is still moving on!.........

This is astack of 4 images taken with a Lumix DMC-Fz7 (not a DSLR) at full optical zoom through a Baader filter. Taken during a short gap in the cloudstowards Salisbury Plain near Fovant, Wilts. A lovely morning, I waited through the cloudy bits listening and watching as 3 larks ascended. A wonderful start to the day.
