From NASA: The sky will put on a stellar show on Nov. 11, 2019, as Mercury crosses in front of the Sun. From our perspective on Earth, we can only ever see Mercury and Venus cross in front of, or transit, the Sun, so it's a rare event you won't want to miss!
For local viewing: View the Mercury transit at Sparks Marina (west peninsula) on the morning of Monday, November 11, 2019 from 6:50 am to 10:00 am. A solar telescope will be available for safe viewing. The transit is visible beginning at sunrise, about 6:50 am at the Sparks Marina.
