Annular solar: 15 Jan 2010, 25° Capricorn; Partial lunar: 26 Jun 2010, 4° Capricorn; Total solar: 11 Jul 2010, 19° Cancer; Total lunar: 21 Dec 2010, 29° Gemini. Times of greatest eclipse are on this page, in UTC.

When is eclipse season in 2010?

24 Dec 2009 to 29 Jan 2010 (north node); 15 Jun 2010 to 22 Jul 2010 (south node); 6 Dec 2010 to 11 Jan 2011 (north node). A season here is every UTC day on which the Sun stands within 18.5° of one of the Moon’s nodes.

Which planets were retrograde during the 2010 eclipses?

Annular solar eclipse on 15 Jan: Retrograde that day: Mercury, Mars and Saturn. It falls on day 21 of a 21-day Mercury retrograde. Partial lunar eclipse on 26 Jun: Retrograde that day: Neptune and Pluto. Total solar eclipse on 11 Jul: Retrograde that day: Uranus, Neptune and Pluto. Total lunar eclipse on 21 Dec: Retrograde that day: Mercury. It falls on day 12 of a 21-day Mercury retrograde.

What is an eclipse season?

The Moon’s orbit is tilted about five degrees to the Sun’s path, so most new and full moons pass above or below the Sun or Earth’s shadow. Twice a year, for about five weeks, the Sun stands near one of the two points where the orbits cross, the nodes; any new or full moon then is close enough to the node to cast or catch a shadow. Every season has at least two eclipses, a solar and a lunar, and sometimes three.

Each wedge spans 18.5° either side of the lunar node the Sun passes in that season, drawn at the node’s place mid-season: the nodes slide back about 19° a year. Solar eclipses sit on the outer ring at the Sun’s longitude, lunar ones on the inner ring at the Moon’s.
