If your skies are clear on Monday night, be sure to check out the southeast sky starting about an hour or so after sundown for an eye-catching sight: Jupiter and the moon shining together.
Weather permitting, stargazers can find the celestial pairing about halfway up in the southeastern evening sky.
You'll immediately see the moon, which will be at its waxing gibbous phase, en route to becoming a full moon for Valentine's Day on Friday. On Monday night, there's a very bright, silvery "star" shining steadily to the right or lower right of the moon. That's not really a star. It's the biggest planet in our solar system: Jupiter.

Jupiter reaches its highest point in the sky — transiting the meridian, as the astronomers would say — around 9:30 p.m. local time. It sets during the predawn hours, soon after 4 a.m. local time.
