Tonight there is a lunar occultation of Mars visible from St. Louis. The Moon and Mars will be visible in the eastern sky just after sunset. Starting at 9:05 pm and ending at 9:52 pm, the Moon will appear to pass in front of Mars. Additionally, the Moon will be full and Mars will be only a few hours away from opposition – at which point it will appear at its largest and brightest in the sky.
This image shows how Mars will pass behind the disc of the Moon tonight. Image credit Pete Lawrence, updated to show accurate times for St. Louis using in-the-sky.org
