Astronomically speaking says you.. I got'a ask, what does that mean??
The dog days are when Alpha Canis Majoris — Sirius, the dog star — is too close to the sun to be visible. The heliacal rising of Sirius before sunrise was viewed by the ancient Egyptians as the sign that the annual Nile flood was about to begin. Being the brightest star in the night sky, it was popularly supposed that when Sirius (whose name means “burning”) was especially close to the sun in its annual procession through the zodiac, the dog star’s heat would supplement that of the sun, making the seasonal warmth especially oppressive. In the Nile delta, Sirius begins to be viewable before dawn about August 6. So the dog days are now over, strictly speaking.
