The sole planet in the evening sky is now Jupiter, which you’ll see low in the west shortly after sunset. Its great brightness lets you see it nearer to the horizon, when we’re looking through more layers of our atmosphere, than nearby stars, none of which are as bright. On the 31^st Jupiter is 14° high in the west 45 minutes after sunset and you’ll easily see it if no structures block your view. On the 6^th it’s 11° high 45 minutes after sunset, so it’s slipping from view and we’ll soon lose it. Be prepared to say good-by to Jupiter later in February.

The planetary action is now in the morning sky where Venus is becoming the brilliant “Morning Star” and Mars is struggling to return to view after a long sojourn behind the sun. Venus is easily visible low in the southeast in morning twilight. Mars is not quite 10° to the right of Venus at a similar height, but it’s precisely 1/100^th as bright so it’s hardly conspicuous.

Mercury is there too, near the horizon to the lower left of Venus, this week and next, but most people who want to see Mercury saw it recently in the evening sky.

These three morning planets are in Sagittarius, a decidedly summer constellation, but you can see it in the morning in winter. Next summer, when the earth is on the opposite side of our orbit, you’ll see Sagittarius in the evening.

The moon is in the evening sky beginning February 2^nd, and that night you’ll find it only 4° to the left of Jupiter. The width of a finger held at arm’s length is about 2° (remember that!) so they’re quite close and you’ll see both together in a pair of binoculars. Then the moon is only 2 days past new, so it’s the slimmest of crescents and it’s only marginally brighter than Jupiter. This is a photo opportunity with the horizon in the same field-of-view; zoom in a little with your camera. Can you see the lunar seas with your binoculars? You’ll have better luck tomorrow and the next night when the moon is higher.

In following days the moon moves through Aquarius and Pisces, huge constellations with no bright stars, so the moon won’t pass near, and be in conjunction with, anything interesting this week.

Notice that the sun sets noticeably later week-by-week (and it rises earlier by the same amount). At the latitude of southern Utah it now sets 1 minute later each day. For weeks surrounding the solstice, the time of sunrise and sunset changes very little, but now the rate of change (the greatest difference from one day to the next) is beginning to accelerate. The rate of change is at maximum at the two equinoxes, and then it slows toward the summer solstice when once again the change is little day-to-day. If you understand sine curves you’ll visualize what is happening.

Thanks to a 2021 grant from the Utah Governor’s Office of Economic Development and the Kane County Office of Tourism, Stellar Vista Observatory offers portable telescopes and tripod mounted binocular kits on loan for free to all residents of Kane County. Nothing beats a quality binocular or astronomical telescope to enhance enjoyment of the night sky!
