Well, if you lived within 16 degrees of the north pole, Sirius won't rise at all for you, ever, so this claim of yours is an empty one!

If you live in a more reasonable location, Sirius will rise twice on one day each year... what do you suppose this indicates?

Go to "Form B", for 'number of days' enter 365, for 'Celestial object of interest' scroll down to Sirius, for location enter 'Dublin' for example,
and hit 'compute data'. After the results are shown, scroll down to October 2nd, where you will find that, from Dublin, Sirius rose at 1 minute after midnight on Tuesday, October 2nd, and then rose again on the same day, October 2nd, at 3 minutes before midnight (and therefore just before October 3rd)... which, it seems, indicates that Sirius will rise 366 times each year. This fact, all by itself, should cause your head to explode!

There must be some logical explanation for this, right? Perhaps the US Naval Observatory is just making this up, or has made a horrible error of some kind... or maybe you are just uneducated enough not to know this, and are just too stubborn to even try to learn about sidereal time.

It is exactly like Neil deGrasse Tyson says...

At some point in time, I hope you decide that astronomers are not as stupid as you seem to think they are, because the fact of the matter is they are as intelligent as people in any branch of science of your choosing, and the sooner you recognize this, the better.

Right now, you have no clue, you just don't know what you don't know.
