Unlike the stars on the American flag, each particular star on the Brazilian flag represents one particular state. All stars are actually present in the night sky, which is depicted as if seen from above (i.e. from outside the illusory 'globe' that the night sky appears to be when seen from Earth), and positioned as they would have been on 15 November 1889 at 08:30 over Rio de Janeiro. There are 5 orders of magnitude (.30, .25, .20, .14 and .10 times 1/14 of the width of the flag respectively). These magnitudes do not directly correspond to the astronomical magnitudes, but are relative to them. (The stars are identified by colour on the image to their right -- these colours do not correspond to their real colour, either astronomically or on the flag)

Data from original annex to Brazilian Law (in Portuguese)
Herman De Wael, 20 January 1998
Star and constellation names translated into scientific and English (and some star names added) by Kjell Roll Elgsaas , 22 January 1998
Some time ago, someone in Brazil wrote to Flags of the World to say that Herman de Wael's
statement that the stars on
the Brazilian flag represent the sky as it was above Rio de Janeiro at 20:30 (i.e., 8:30 in the evening)
on 15 November 1889 was incorrect. [This statement has since been corrected, above--Ed.]
The writer stated that the time was correctly 08:30 (i.e., in the morning).
article in Portuguese by a Brazilian astronomer, Professor Paulo Araújo Duarte of the
Federal University of Santa Catarina, bears this out, saying "In truth, the creators
of our republican flag intended to represent the stars in the sky at Rio de
Janeiro at 8:30 in the morning on 15 November 1889, the moment at which the
constellation of the Southern Cross was on the meridian of Rio de Janeiro
and the longer arm [of the cross] was vertical." Another article,
citing "O Céu da Bandeira (The Sky of the Flag)" by J. R. V. Costa says the precise hour was actually 08:37.
This last article is one of the best overall discussions of the history of the
Brazilian flag anywhere; it includes the designer of the flag's
explanation of his intentions, at least regarding the stars.
Joseph McMillan, 2 August 2002
My original thought was the same as Jaume's--who would put the stars
on the flag as seen at a time of day when they couldn't be seen?
(And I don't believe there is any time of year when the stars are
visible over Rio at 8:30 in the morning.) However, Jorge Candeias has made clear that the
expression no dia in this context in the legislation means "in the morning."
It now seems to me that there are three pieces of evidence, each
strong in its own right and collectively conclusive, that the stars
on the Brazilian flag are intended to represent the sky over Rio at
8:30 a.m. on 15 November 1889, not at 8:30 p.m. (20:30) that evening:
I think that's indeed the more likely possibility. It could also be a
post-factum thing: since an upright Cruzeiro makes a better symbol than a
Cruzeiro in some other position, it was adopted without further thought.
Later on, after being asked repeatedly about the meaning of the symbol,
someone cooked up that explanation as a fancy way to keep meaning-buffs
