The Full Moon celebrates Jupiter’s coming opposition by accompanying the bright planet in a beautiful conjunction tonight.
Even last night Jupiter and the Moon were close enough to attract attention. Tonight they’ll be even more striking. Two reasons for that. The Moon is full this evening and will have crept within 41/2° of the planet. They’ll rise together and roll together all night long.
February’s full moon is aptly named the Full Snow Moon as snowfall can be heavy this month. Just ask the folks in Chicago. The Cherokee Indians called it the “Bone Moon”, named for the tough times experienced by many Native Americans in mid-winter when food supplies ran low. With little left to eat people made use of everything including bones and bone marrow for soup.
Not only is the Full Moon directly opposite the Sun in the sky, rising around sunset and setting around sunrise, but in mid-winter they’re nearly on opposite ends of the celestial seesaw.
In early February the Sun is still near its lowest point in the sky (bottom of the seesaw) for the northern half of the globe. And while daylight is steadily increasing as the Sun moves northward, darkness still has the upper hand this month. Full Moons like tonight’s lie 180° opposite the Sun, placing the Moon near the top of the seesaw. Come early August, the Sun will occupy the Moon’s spot and the Full Moon will have slid down to the Sun’s current position. Yin and Yang folks.
Now here’s the interesting thing. Jupiter will also be in “full moon” phase when it reaches opposition this Friday Feb. 6. Take a look at the diagram. From our perspective on Earth, Jupiter and the Sun lie on opposite sides of our planet 180° apart. As the Sun sets Friday, Jupiter will rise in the east and remain visible all night until setting around sunrise exactly like a Full Moon.
So in a funny way, we have two Full Moons this week only one’s a planet.
Like me, a lot of you enjoy a good moonrise. That golden-orange globe, the crazy squished appearance at rising and the transition to the bright, white, beaming disk that throws enough light on a winter night to ski in the forest without a headlamp. All good reasons to be alive.

As you step outside tonight to get your required Moon and Jupiter-shine, consider the scene if we took neighboring Jupiter and placed it at the same distance as the Moon. A recent series of such scenes was released by the Russian Federal Space Agency (Roscosmos). I included one here and added the Moon for you to compare. Is Jupiter enormous or what?
Hey, I noticed this last night myself as well! Looked very awesome, so took a picture as well(from Greater Toronto Area, Ontario, CA), Although, didn’t turn out quite as nice. What are the odds of having all things appear same night? (Jupiter in conjunction at near opposition plus inside the moon’s halo?!)
Magibby87,
So you had high clouds and a halo, too. Nice, wasn’t it? This was the view from Duluth. We saw the halo most of the night. I took photos earlier, but checked again shortly before going to bed at around 11:45 p.m. Holy heck, the halo was so much better, so I grabbed the camera for another round of photos. What the odds? Good question – small for sure!
Yes, it was quite a sight! Always find the halo around Sun and moon quite impressive. And yea, the halo was visible all night up here as well. But now that I know Jupiter is at opposition, and closest approach, I have to get the telescope out over the next few days. Thanks for posting this story and replying as well!
You bet Magibby87. Appreciate your comments.
I didn’t see it myself, but it was also visible from much of Britain:
