Southern Colorado Skies / September 24 – 30, 2017

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


Look for the Moon as it passes through Ophiuchus and comes very close to Saturn on September 26th.

Tuesday (September 26)

Look for Saturn below the Moon this evening (see above graphic).

Wednesday (September 27)

First-quarter Moon at 8:54 p.m. MDT.

Thursday (September 28)

Now the Moon shines above “teapot” of Sagittarius.




Mercury (Leo):

Mercury is dropping below Venus and Mars and gradually fading into the sunrise this week. (I was fortunate to get a decent photo of the Venus-Regulus-Moon-Mars-Mercury alignment last Monday morning.)

 Venus (in Leo):

Venus is still a brilliant “morning star” before and during dawn, but it is dropping fast in elevation.

Mars (in Leo):

Very low at dawn (binoculars may be required – beware of the rising Sun!), below Venus. (Mars and Venus will pass closely by each other on October 5th.)

Jupiter (in Virgo):

Jupiter is very low on the west-southwestern horizon during sunset and sets as night begins. Binoculars may be required – beware of the setting Sun!).

Saturn (in Ophiuchus):

Saturn is visible in the south-southwest after nightfall.

Uranus (in Pisces):

High in the east by late evening.

Neptune (in Aquarius):

High in the southeast by late evening.


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:

Sunday (September 24) 7:23:51 p.m. / Magnitude -4.8 /N / Elevation 51 degrees

Monday (September 25) 7:17:13 p.m. / Magnitude -1.4 / N / Elevation 52 degrees

Monday (September 25) 7:17:43 p.m. / Magnitude -2.3 / N / Elevation 52 degrees


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