Great opportunity for Asteroid Observing tonight

14. 04. 11

Newly-discovered asteroid 2011 GP59 is due to make its closest approach to Earth on April 15 at 19h GMT, however the asteroid will actually be brightest tonight at around Midnight, when it will be very favourably placed in the sky for observers worldwide. This is one of the best examples of an NEO close approach for a few years and will easily be bright enough to be well observed in a large (>0.2m aperture) telescope when it will appear as a faint slow-moving star.

Observers should also note that the object, which is approximately 60 metres in diameter, appears to be rotating very quickly, and this - combined with its distinct oblong shape - will mean that it will appear alternately very bright then very faint every four minutes or so.

More information can be found on the British Astronomical Association website.
