The Great Shefford Observatory is a private astronomical
observatory situated in West Berkshire,
England, about 60 miles west of central London, run by me, Peter Birtwhistle. |
The observatory has been fully operational since 26 May 2002
(see our first light image at right) with a 12" diameter telescope and electronic camera (CCD).
A programme of astrometry was started on 30th May
2002. Observatory code J95 was allocated to Great Shefford Observatory by the Minor Planet Center in June 2002. In June 2005 the 12" telescope was upgraded to a 16" and in September
2005 the CCD was also upgraded, allowing
fainter objects to be detected. |
|
The work done at Great Shefford is primarily:
-
following up newly discovered Near-Earth Objects (NEOs) to
help improve their orbits so their position can eventually be predicted far
into the future to check they don't endanger the Earth
-
cometary astrometry, concentrating on the fainter objects
that don't get quite so much attention as many of the brighter objects.
Other
objects are also imaged, including Gamma Ray Bursters, Supernovae, some unusual man-made
satellites and deep sky objects.

I've been doing and check out the What's new page for

Meteor photobombs Apollo object 2017 TN6 on 28 April 2024
13 x 12 sec exposures, field 18' x 18', 0.4-m Schmidt-Cass + CCD
A meteor crosses the field while potentially hazardous Apollo asteroid 2017 TN6 was being imaged
on 28 April 2024.
The ionised trail left behind in the upper atmosphere drifts out of view over the
next 2 minutes and 40 seconds.
(The asteroid is too faint to see in the individual images)
