|2007 BD7 is a potentially hazardous Apollo minor planet,
discovered on 2007 Jan 23 by Brian Skiff at the Lowell Observatory using
the 0.59-m LONEOS Schmidt at magnitude +17.6, well placed in the
opposition area of the sky, at the high northern declination of +49°.
It was announced in MPEC
2007-B36 at 12:07 UT on 2007 Jan 24.
2007 BD7 was approaching the Earth at discovery, passing about 17 times the
distance of the Moon on 2007 Feb 08.6 UT, disappearing from view into
the evening twilight just a few days later.
The image above was obtained two days after discovery as part of the
ongoing NEO follow-up program at Great Shefford. Immediately the first
images were obtained the two brightest parts of the planetary nebula
were noticed and identification made with the large Planetary Nebula PK
164.8+31.1 = Jones-Emberson 1, discovered in 1939.
A spectacular, high resolution colour image of this Planetary can be
taken using a 20" Ritchey-Chrétien telescope at the National
Optical Astronomy Observatory at Kitt Peak by Adam Block/NOAO/AURA/NSF.
The image has North up but East to the right, rather than to the left as
in the image above.
