Tonight should be our sidewalk night in Monrovia, but the clouds won't clear until 8 p.m. and there is a line of small but powerful thunderstorms between us and Antelope Valley.  So we are cancelling tonight's sidewalk astronomy to protect our telescopes, and not disappointing our guests with poor views of the moon. Next dates are June 8 and 15. If, you happen to look up and see the moon from home or from your evening stroll tonight, you can use these links below to identify features with your unaided eye. The moon is at First Quarter tonight May 11, 2019 at 6:12 pm. You can find the phases of the moon every month in What's Up video from JPL now. And I've included the link to my very favorite moon map below. What's Up video ends with the month's moon phases - a great addition to the video!  https://youtu.be/VoivZE4xLEw Time and date  -- a calendar of lunar phases for the year, just select your location for precision: https://www.timeanddate.com/moon/phases/ --> Moon Map I love!  The awesome Lunar and Planetary Sciences Lunar Landing Site Chart: https://www.lpi.usra.edu/resources/mapcatalog/LandingSite/ Next sidewalk dates are June 8 and/or 15, weather permitting.
