Hey all,

I havent seen this posted yet..
(unless I am posting it in the wrong forum)
If so, I do apologize.

Anyway..
If you see a 'faint, slowly moving star" in the sky tonight..
Chances are it is Asteroid 2011 GP59,

2011 GP59, as seen on April 12, 2011 by E. Guido & G. Sostero. ClickHere to see more on this NEO from the Remanzacco Observatory in Italy.




A newly discovered asteroid could provide one of the best recent viewing opportunities for amateur astronomers, according to the British Astronomical Association. “This is the best NEO close approach these past few years and is bright enough to be observed visually in large (>20cm., or 8-inch) aperture telescopes when on the night of Thursday 14th it will appear as a faint slow-moving star,” writes Richard Miles, the director of the BAA’s Asteroids and Remote Planets Section.




See a new picture of asteroid 2011 GP59 from Ernesto Guido & Giovanni Sostero taken on April 14, 2011, below.



“It’s a single unfiltered exposure of 600 seconds, showing 2011 GP59 as trail with brightness fluctuations clearly evident,”





2011 GP59 was discovered just a few days ago and will make its closest approach to the Earth on April 15 at 19h UT at 1.39 lunar-distances. But it will be brightest at an average magnitude of 13.2 around 00h UT on the night of April 14/15 when Miles says it will be very favorably placed in the sky for observers worldwide.
The asteroid is approximately 60 meters in diameter and appears to be rotating very quickly, about once every 7.35 minutes. Its oblong in shape and rotation will vary the object’s brightness every 4 minutes or so.

Miles reported that David Briggs observing with the Hampshire Astronomy Group’s 0.4-m instrument on the evening of April 11 commented, “This is probably the fastest rotator I’ve seen so far in that it completely disappears from view every 3 to 4 images.”




Also,
Get ready for some "TLP"! (Transient Lunar Phenomena)




The British Astronomical Association is also seeking observations of the Moon on Friday, April 15, between 19:00 and 21:00 UT, when the Aristarchus and Herodotus area of the Moon will match the same illumination, to within +/- 0.5 degrees, as that observed during the famous Transient Lunar Phenomena (TLP) seen by Greenacre and Barr from Flagstaff observatory back on Oct. 30, 1963.

TLPs are very short changes in the brightness of patches on the face of the Moon, which can last anywhere from a few seconds to a few hours and can grow from less than a few to a hundred kilometers in size. This phenomenon has been observed by hundreds of amateur and professional astronomers, but how and why this occurs is not understood. Some astronomers believe that they are the outcome of lunar outgassing, where gas is being released from the surface of the Moon, but most commonly astronomers think it could be an effect from Earth’s own atmosphere.

If you want to help understand TLPs and perhaps observe an event like this for yourself, the BAA Lunar Section is looking for high resolution monochrome, or especially color, images of this area during this time period,, which favors observers in Europe.



But you can check this website ~ users.aber.ac.uk... from the University of Aberystwyth for many locations around the world of when would be a good time to observe a TLP.

Hope you get to see the show!
Clear skies!

My one and only BUMP to the top,
For those who havent seen it and would like to try and spot the Asteroid.
So, Bump.

Hope you have clear skies!

Skies are pretty clear here at the moment.

You do realize that you would need to be looking through a telescope to even stand a chance of seeing it?

From the source you posted:

But it will be brightest at an average magnitude of 13.2 around 00h UT on the night of April 14/15 when Miles says it will be very favorably placed in the sky for observers worldwide.


Even under a perfectly light pollution free sky the faintest objects that the human eye can perceive are around 7th magnitude, which is significantly (hundreds of times) brighter than magnitude 13.2.

In case anyone is wondering why they could not see it....
