On the morning of February 12, the thin crescent Moon, less than 5% lit, will be 4.5° to the upper left of Mercury. This should provide an excellent guide to locating the planet. Using a binocular put the Moon to the upper left of the field of view, Mercury should then be towards the lower right. Mercury will remain visible long after all stars have disappeared in the brightening sky.
By the end of February, Mercury will be rising some 70 minutes before the Sun, so will be lower in the morning twilight, only 3° above the horizon 45 minutes before sunrise. This will make it a difficult object even though it will be at magnitude -0.6.
On the 17th Venus will be just over half a degree above Jupiter. But Venus will be only 4° up at sunset. The two planets will be little more than 8° from the Sun, so do not look for them until the Sun is set. Viewing the Sun directly through binoculars could lead to instant eye damage.
In February, Mars will be in Cancer, starting the month some 3° below the Praesepe (Beehive) star cluster. During the month it will move slowly towards Gemini, ending the month about 8° to the right of Pollux which, at magnitude 1.2, the brightest star in Gemini. The star will be a little fainter than Mars, but have a similar slightly orange colour.
On the 26th the nearly full Moon, 92% lit, will be about 5.5° to the upper right of the planet.
SeeVenus for the conjunction of the two planets on February 17.
During February, Saturn will be moving slowly to the west, that is in a retrograde sense, through the stars, an effect due to the faster moving Earth overtaking Saturn. The planet is in Virgo, some 20° from the first magnitude star Spica. The Moon will be about 7.5° from Saturn on the night of February 2/3, best seen before sunrise on the morning of the 3rd, when the Moon will be to the upper left of Saturn. At midnight the two will be slightly further apart with the Moon nearly directly above the planet.
Saturn's rings are still only open a slight amount, so will generally appear as a bar either side of the planet in a small telescope.
