Half an hour after sunset on the 1st, Uranus, in Pisces, is about 20° above the horizon. By midmonth, it will have essentially disappeared into the twilight after sunset.
Jupiter becomes visible shortly after (or, perhaps, even before) sunset. It lies almost overhead in the early evening. At midmonth, it doesn't set until 3:30 am EDT. At magnitude -2.3, it is the brightest point of light in the sky until Venus rises in the early morning. Even a small telescope reveals the two main dark belts - the North and South Equatorial Belts - on either side of the planet's equator. Larger scopes reveal numerous others. The four large Galilean satellites - Io, Europa, Ganymede, and Callisto - are always changing their positions. As Jupiter becomes visible after sunset on the 16th, a shadow transit of both Io and Ganymede is well under way; Io's shadow finally leaves the planet's disk at 8:37 pm. Between 10:08 pm and 10:32 pm on the 23rd, the shadows of Io and Ganymede are again visible on the planet simultaneously.
Mars is getting ready for its grand entrance onto the stage. At the beginning of March it rises about 9:30 pm (local standard time), or about four hours after sunset. By the end of the month, it comes up at about 8 pm (local daylight time), or just 40 minutes after sunset. Mars is approaching its once-in-every-26-months opposition, which occurs on April 8th. Opposition is the orbital configuration in which the Sun, Earth, and Mars are lined up in a straight line. Since, from the point of view of us on Earth, Mars and the Sun are opposite each other, it follows that, at opposition, the planet must just be rising as the Sun is setting on the opposite horizon, must remain up throughout the night, and be setting just as the Sun comes up on the opposite horizon. A more important implication is that opposition is the time when the Earth and the planet are the nearest to each other. The planet then appears at its brightest and largest. Mars is not quite at that point yet, but during March it doubles in brightness, from magnitude -0.5 to -1.3. However, from the viewpoint of telescopic observers, the best part is the fact that Mars is growing dramatically in size. On March 1, it subtends an angular diameter of 11.6 arc-seconds; by the 31st, it will have grown to 14.6" in diameter. (That, by the way, is not far short of the maximum size - 15.1" across - it will attain at opposition.) For those trying to discern the surface features on Mars, this is about as good as it gets - at least at this opposition. (We'll have to wait patiently until the next opposition in 2016 to see it get as large as 18.4" across, or better yet, the 2018 opposition when the planet will swell to 24.1" across.) As soon as this month, however, we should be able to make out considerable surface detail on Mars. Its Northern Hemisphere is tilted toward us, so the North Polar Cap will probably be the easiest feature to make out. It is now early spring in the Martian north, so the cap will be slowly melting; the layer of carbon dioxide frost covering the cap sublimates into vapor in the warmer temperatures, but the water ice cap underneath never completely disappears. Some of the larger dark albedo features, such as Syrtis Major and Mare Acidalium, will be the ones most easily visible. Consult some charts and maps and see how many features you can identify. And enjoy the view!
And speaking of enjoying the view, you might want to wait two and a quarter hours or so after Mars rises to see that most splendid of planets, Saturn. The ringed planet is slowly making its way toward its own opposition, which it will reach on May 10th. Meanwhile, however, Saturn is already at magnitude +0.3 - bright enough to outshine any of the stars of its host constellation, Libra. The view through a telescope is much more impressive, though. The planet's globe is about 18" in diameter, while the visible rings - tilted toward us by about 23° - are about 40" across.
In the morning sky, brilliant Venus reaches greatest elongation (47° W of the Sun) on March 22. Unfortunately, low inclination of the ecliptic this time of year means that Venus' distance from the Sun doesn't necessarily translate into altitude above our horizon. Even during its greatest elongation, Venus lies only 15° above the horizon a half hour before sunrise. That doesn't take anything away from its brightness, mind you. It dims somewhat from magnitude -4.8 to -4.4 during the month - but even at its worse, it is still a full two magnitudes, or a factor of over six times, brighter than Jupiter gets this month. A telescope shows Venus shrinking during March from a disk 33" across and 36% illuminated to one 22" wide and 54% illuminated.
Like, Venus, Mercury also reaches greatest elongation (28° W of the Sun), in this case on March 14. For the same reason as Venus, it also hugs the horizon in spite of its angular distance from the Sun. On the 14th, it is only 5° above the horizon a half-hour before sunrise, making it a difficult target to spot, at best. If you do manage to see it through a telescope, you'll see a disk just 7.3" wide and 55% illuminated.
Neptune is too close to the Sun to be easily observable most of this month.
Pluto, in Sagittarius, rises about two and a half hours before sunrise at midmonth; an hour before sunrise, it will have attained an altitude of just 20° above the horizon - making the planet extremely difficult to see.
The dwarf planet/asteroid 1 Ceres, in Virgo, brightens from magnitude 7.7 to 7.1. At midmonth, it rises before 9:30 pm EDT, and says up most of the night. It lies about 12.5° to the NE of Mars
The asteroid 4 Vesta, also in the constellation Virgo, remains just 2.5° west of Ceres. Vesta is about 9.5° to the NE of Mars; it brightens from magnitude 6.6 to 5.9. On March 26-27, Ceres, Vesta, and a fourth-magnitude star Tau Virginus form a line, with the asteroids on either side of the star.
The asteroid 2 Pallas, in the constellation Hydra, is past last month's opposition but is almost as bright - magnitude 7.0; in fact, it is brighter than it any time between 1991 and 2028. On March 1, it passes just 3° to the east of 2nd-magnitude Alphard, Hydra's brightest star. By the end of the month, Pallas will have faded to magnitude 7.6.
