Consider a planetarium program to help you plan your observations. There are many commercial products available; an excellent program (STELLARIUM) is available free at


The Moon makes its way through Taurus mid-week.


Monday (August 14)

Last-quarter Moon at 7:15 p.m. MDT. The Moon rises around midnight.

Tuesday (August 15) – Thursday (August 17)

Look for the Pleiades (M45) above the Moon’s upper left and Aldebaran (in Taurus the bull) directly below the Pleiades (see above graphic). Below all this is Orion (winter is coming!).




Mercury (in Sextans):

Lost in the glare of the Sun.

Venus (in Gemini):

Look for very bright Venus in the east before dawn. To Venus’ left (east) you can see Pollux and Castor (in Gemini the twins), while high above you can see the Pleiades star cluster (M45).

Mars (in Cancer):

Invisible within the glare of the Sun.

Jupiter (in Virgo):

Jupiter is very low in the west-southwest as night begins.

Saturn (in Ophiuchus):

Saturn is visible low in the sky in the south after nightfall. It’s to the upper right (west) of the Sagittarius “teapot.”

Uranus (in Pisces):

High in the southeast before dawn.

Neptune (in Aquarius):

High in the southeast before dawn.


The following data are based on my location in Pueblo West, Colorado. If you live well outside this area, you should consider checking this information for your location in order to be assured of accurate times, elevations, etc. If you’re unfamiliar with Iridium flares, check out my article at:

These are too numerous to list here! If you’re serious, load the ISS DETECTOR app on your smart phone or tablet.
