About a week after its first appearance (heliacal rising) in the morning sky, Sirius, the night’s brightest star, shines from the east-southeast nearly 40 minutes before sunrise.

As seen in the image above, Sirius is low in the sky.  Find an observing spot reasonably free of obstacles to see the star. It is easily visible without a binocular or telescope.  As the star rises 4 minutes earlier each day, find in higher in the east-southeast at the same time in about a week.

Here is a daily summary about the planets during August.
