11/10/2020 – Ephemeris – Mercury will reach it greatest separation from the Sun in the morning today

November 10, 2020 Comments off

This is Bob Moler with Ephemeris for Tuesday, November 10th. Today the Sun will be up for 9 hours and 45 minutes, setting at 5:19, and it will rise tomorrow at 7:35. The Moon, 2 days past last quarter, will rise at 2:42 tomorrow morning.

Mercury will reach its greatest western elongation from the Sun near noon today (17:00 UT). That means it was visible this morning before sunrise in the east. And will be visible again tomorrow morning. The next Mercury greatest elongation will be January 24th, next year. It will be a greatest eastern elongation, which will be visible in the western sky in the evening after sunset. So western elongations are seen in the east and eastern elongations are seen in the west. The “from the Sun” is usually omitted in astronomical lists of events, but implied. Sounds a bit confusing, but it makes weird sense. Mercury’s morning appearance will last about a week before it get too low to easily spot, below and left of Venus.

The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Addendum

Mercury, Venus, Moon tomorrow morning at 6:30 am

Mercury, Venus, Moon tomorrow morning November 11, 2020 at 6:30 am. The orange line is the ecliptic, the plane of the Earth’s orbit. It is the path of the Sun in the sky, The Moon and planets also stick close to that line. The Moon is a crescent, though that can’t be seen at this scale. Over the next week Venus and Mercury will slide downward along the ecliptic in relation to the stars, as will the Moon at greater speed. Created using Stellarium.
