Yes indeed Laura, since you daughter could not work out what it was, it was an unidentified flying object. (Maybe it wasn't flying, but the image seemed to be?)
Was it a spacecraft piloted by intelligent beings from somewhere else in the Universe? - very very highly unlikely.
Could it be explained if more information was available to your daughter, you and others? - very very likely.
There are lots of lots of things seen that aren't identified or readily explained by those that see them. But the vast majority do have an explanation.
See this extract from Wikipedia's entry on UFOs:-
Studies show that after careful investigation, the majority of UFOs can be identified as ordinary objects or phenomena (see
Identification studies of UFOs). The most commonly found identified sources of UFO reports are:
- Astronomical objects (bright stars, planets, meteors, re-entering man-made spacecraft, artificial satellites, and the moon)
- Aircraft (advertising planes and other aircraft, missile launches)
- Balloons (weather balloons, prank balloons, large research balloons)
Much less common sources of UFO reports include:
A
study by the
Battelle Memorial Institute of US Air Force reports included these categories as well as a "psychological" one. However, the scientific analysts were unable to come up with prosaic explanations for 21.5 % of the 3200 cases they examined and 33 % of what were considered the best cases remained unexplained, double the number of the worst cases. (See full statistical breakdown in
Identification studies of UFOs). Of the 69 % identifieds, 38 % were deemed definitely explained while 31 % were thought to be "questionable." About 9 % of the cases were considered to have insufficient information to make a determination.
The official French government UFO investigation (GEPAN/SEPRA), run within the French space agency CNES between 1977 and 2004, scientifically investigated about 6000 cases and found that 13.5 % defied any rational explanation, 46 % were deemed definitely or likely identifiable, while 41 % lacked sufficient information for classification.
An individual 1979 study by
CUFOS researcher
Allan Hendry found, as did other investigations, that only a small percentage of cases he investigated were hoaxes (<1 %) and that most sightings were actually honest misidentifications of prosaic phenomena. Hendry attributed most of these to inexperience or misperception.
[49] However, Hendry's figure for unidentified cases was considerably lower than many other UFO studies such as
Project Blue Book or the
Condon Report that have found rates of unidentified cases ranging from 6 % to 30 %. Hendry found that 88.6 % of the cases he studied had a clear prosaic explanation, and he discarded a further 2.8 % due to unreliable or contradictory witnesses or insufficient information. The remaining 8.6 % of reports could not definitively be explained by prosaic phenomena, although he felt that a further 7.1 % could possibly be explained, leaving only the very best 1.5 % without plausible explanation.

There are much more exciting things to see in the sky. Perhaps your daughter would like some binoculars or a telescope to see incredible things - beyond our galaxy even!
