gosh, its a pity you cant see it, I have to say its very good, the best "what the hell is that" video I've seen in a long time.
I had to download a new codec for windows to run this, but it did run afterwards.

1. Taking Albert's angular estimate of 0.1 Arc Min.

2. Assume that a reasonable diameter for a child's party balloon is 0.3 meters .

3. We can calculate that we are looking at a party balloon drifting just
10.3 Km away.

4. Its rate of drift is exactly consistent with being blown around in the wind.

Apparently research has been done in this field by the astronomer Arkhipov. This is the paper partly reprinted fron the "Strolling Astronomer"
Sorry that this is long, but I thought it would be a useful information. Alot of material has been left out from the main part. It provides a flavour in light of our discussions. Hence also Diagrams, figures and tables are left out. Of course more details can be grabbed by obtaining the journal from ALPO.

Fast Moving Lunar Phenomena
By: Alexey V. Arkhipov, Institute of Radio Astronomy, Kharkov
Reprinted from the "Strolling Astronomer", Feb 1997
Volume 39, Number 3
Abstract
From time to time reports have appeared in the literature describing fast- moving objects (FMOs) moving across or near the lunar surface. Typically, these take the form of either light or dark spots, with apparent velocities of 0*.001-0*.1/sec. and a duration under one minute. We have evaluated the hypothesis that such phenomena are of terrestrial origin and only appear projected against the Moon by chance. Statistical analysis, however, reveals a significant excess of sightings in the Mare Imbrium area relative to the Mare Nectaris-Foecinditatis area. These unexpected results, as well as the trajectory angle of some of these objects, imply that FMOs may be of lunar origin. Clearly, further systematic patrols are warranted.

Introduction
This article addresses the phenomenon of sporadic, fast-moving objects (FMOs) which reportedly appear and disappear across and near the lunar disc. Observations of birds, insects, terrestrial meteors, and so forth that occasionally pass across the line of sight have naturally been excluded from this analysis. FMOs have been reported by a number of prominent observers, including Schroeter (1791), Schafarik (1885), Haas (1947) and Firsoff (1960). They have been listed in the NASA Lunar Transient Phenomena Catalogue (Cameron 1978).

Scharfarik (1885) emphasized the difference between terrestrial meteors and the star-like FMOs in the following report:
“In class I, I should place an object of so peculiar a character that I do not know what to make of it. 1874, April 24, at about 3 1/2 h.p.m. I observed the moon (illuminated nearly 3/4 in bright sunshine, with power 66, field 34’, of a fine 4-inch achromatic by Dancer, when I was surprised by the apparition, on the disc of the moon, of a dazzling white star, which traveled slowly from E.S.E. to W.N.N., and after leaving he bright disc, shone on the deep blue sky like Sirius or Vega in daylight and fine air. The star was quite sharp and without a perceptible diameter... It was absolutely sharp, and its flight so slow ( about 5 s.) that even a trace of indistinctness would have been perceptible.”

Haas (1947) argued that fast-moving lunar objects exhibited properties statistically different from those of terrestrial meteors, particularly with respect to their short path lengths and small angular dimensions. In the 1940’s, he thought that meteors could actually be observed in the lunar atmosphere, although it is now clear that such an atmosphere is far too rarefied for this to occur. It is primarily for that reason that most modern observers a priori favor a terrestrial explanation for FMOs. this postulate can be usefully tested, however.

FMO Categories
Although the author has collected reports of fast-moving objects on the Moon for many years, including observations recorded in the literature as well as direct correspondence with individual observers, to date only 114 cases have been compiled. Reports of FMOs are indeed rare and comprise only about 5 percent of current reported lunar Lunar Transient Phenomena (LTP). From an analysis of the available LTP reports, Arkhipov (1994a) recognized three types of moving objects:

(a) Permanent lunar spots exhibiting very slow movement due to
libration and periodic illumination effects.
(b) Cloud-like objects, lasting several minutes to three hours, with
angular velocities of *.0000001-0*.001/sec., and possibly the
result of charged dust paricles rising in electric fields on the
lunar surface.
(c) Fast-moving objects, lasting<1 min. and moving between
0*.001-1*/sec.
Only the latter category constitutes a sample large enough to warrant statistical evaluation. Accordingly, only FMOs whose duration and location on the lunar surface have been reported were selected for the analysis (see Table 1, p. 136). In Table 1: Xi=cos (latitude) x sin (longitude); Yi= sin (latitude ); the rectangular coordinates of the starting (i = 1) or the terminal (i = 2) points of the FMO trajectories; n = the number of objects or clusters of objects; t = duration of the event; * = personal communication with the observer ( from the author’s files).
.
FMO Distribution on the Moon
Since only 66 usable data points were available from our list, a contour-smoothing technique had to be utilized to demonstrate FMO distribution patterns across the lunar surface. The number (k) of points inside a circle with a circle of 0.3 lunar radii was calculated. This procedure was applied by scanning the entire lunar disc with this circle. For every position of the circle center, the ratio (f) of k and its average value were calculated. The resulting map of the f parameter is shown in Figure 1 (p.137).
Table 1
The only statistically significant feature on the map is the excess of points in the Mare Imbrium region (A) relative to the Mare Nectaris-Mare Foecunditatis region (B). Indeed, 19 data points fall inside the f=1.5 contour of Region A. The area within this contour constitutes 0.131 of the entire visible lunar disk. The probability that >19 points would fall within this contour by chance on the basis of the binominal distribution is found as follows;
(See formula at Figures link)
where M=19 and N=66. This gives a probability of 0.0006. With respect to Region B only one data point falls within the f<0.5 radius, yeilding a probability of <1 point inside this area, comprising 0.148 of the visible surface, of W*=0.0003. Obviously these calculated probabilities are sufficiently low to contradict the expected uniform distribution of FMO events should they be of terrestrial origin.
The apparent correlation of FMO events with certain lunar regions for what are presumably random events is certainly unusual, however, possible selection effects must also be considered.
First, it is possible that the probabilty of observing lunar meteors is affected by the albedo of the lunar background. The ratio of the visual albedo of the brightest crater Aristarchus to the darkest Grimaldi, is only 3 or a magnitude difference of 1.19 (Fessenkov, 1962). The cumulative number of meteors brighter than magnitude m is proportional to 10*.**m for -10<m<+10 (Astapovich, 1958). Consequently, the background effect cannot account for the differences in meteor visualization by a factor of 10*.*x1.19 or 2.28 times. The average value of the f-parameter is M/Np=2.20 in Region A (where f>1.5). Clearly the lunar background differences cannot account for a 22-fold difference.

Figure 1 - Contour map of the relative density (f) of the star & end points of FMO trajectories across the lunar disk, where 1.0 is the mean of f. The selenographic orientation is also indicated.
Second, some regions of the Moon might be observed more frequently due to favorable solar illumination and the restricted field of view of the telescope. However, lighting conditions should be identical for the lunar Southern and Northern hemispheres, yet there is assymetry with respect to the distribution of points; 39 in the north and 25 in the south. The probability of such a difference being due to chance is 0.052 (M=39; N=64; p=0.5), implying at a 95 percent confidence level that the north-south asymetry is real. in addition, most observers whose data were analyzed here, used small telescopes with low magnification, and thereby examined almost the entire lunar disk. Conceivably, the search for LTP in the Plato region could draw an observer’s attention towards Mare Imbrium, resulting in an unintentional bias toward observing that area. However, Aristarchus, the “Mecca” of all LTP hunters (Cameron 1977), is outside region A, suggesting such a bias is in fact unimportant in this context. Collectively, the above indicate that biased selection effects do not explain the reported asymmetry in FMO distribution patterns.
Finally, some FMOs exhibit curved, nonmeteoric trajectories. Let me cite one such original report. On 1995 AUG. 15, using a small refractor, Yaremenko (1983) stated: “A luminous body similar to a 3rd magnitude star flew at about 0.2 lunar radii above the disk, parallel to its edge (limb). The body flew about a third of the circumference (it continued for 4-5 seconds) and [apparently] landed on the lunar surface with a steep trajectory.” his drawing is reporduced in Figure 2. Similar examples of paths are shown in Figure 3-5 (p. 138). Although curved trajectories are very rare events, they must be taken into account.
.
Conclusions
Reports about lunar FMOs clearly warrant serious attention. It can be argued that at least some FMOs occupy circumlunar locations, but clearly more data are needed before this can be verified. The author would greatly appreciate receiving reports about any moving phenomena in the vicinity of, or over, the lunar disk. Please contact: Alexey V.

If that was near the Moon Eamon we need to rewrite our physics books.
Or start believing in exotic alien technologies.

The object was seen in Busto Arsizio on 29 April 2007

History Quote:

"When, on 25 April 1945, the partisans took over, Busto Arsizio thus gave voice to the first free radio channel in northern Italy since the advent of Fascism."

On 25th April 2007 Liberation Day celebrations in Busto Arsizio released thousands of balloons!

Fits the bill as an ordinary balloon about 10Km away!

Then again...maybe it isn't !

If it is a massive object near the moon, its a small bit surprising that there is no shadow ?
Of course, it's shadow could have missed the moon, still, I don't buy the space ship idea, it looks like a balloon to me.

Hi

If you are having issues playing this it's probably down to Windows Media Player being the worst piece of cr*p out there.

You need the Divx codec which you get here :

www.divx-digest.com/software/divxcodec5.html#downloads

Use the Divx player that comes with the standard download and it works first time.

Hope this helps
