The constellation Aquarius can be seen during September evenings in the southern sky. Perhaps the recent rains are from another pouring from the Water Bearer.
The Aquarius myth follows the story of Ganymede, a young prince of Troy. Zeus kidnaps Ganymede and decides that Ganymede will become his personal cup-bearer bringing him drinks whenever he pleases. One day Ganymede has had enough and he decides to pour out all of the wine and water of the gods. All that liquid falls to Earth as endless rain for days upon days. In a rare moment of self-reflection, Zeus realizes that he has been a bit unkind to the boy, so he makes him immortal as the constellation Aquarius, the Water Bearer.
Aquarius is not a prominent constellation but you can find it by drawing an imaginary line through Scheat and Markab in the square of Pegasus, down about 10° to a point below the circlet of Pisces and then look a little to the right to find 3 stars marking the water jar.
If you have a telescope then the globular cluster M2 is located a few degrees to the north of Sadalmelik, the brightest star in Aquarius.
This year, Neptune is located in Aquarius between the 4.2 magnitude star Phi-Aqr and the 3.8 magnitude Hydor.
