I was reviewing the July article yesterday and realized I completely MISSED the Total Eclipse this month. (My apologies to Eastern Asia, Japan and the South West Pacific) . I have fixed the article and included the Total Solar Eclipse.
Archive for July, 2009
In the very early morning hours of July 7th a very slight Penumbral Lunar Eclipse will be visible from the Pacific rim, including western South America, the West Coast of Mexico and South Western United States, Hawaii, New Zealand, eastern Australia and the Pacific side of Antartica.
The New Moon for July is Tuesday, July 21st. This will make the weekend of July 18-19th as the best weekend for dark sky observing.

Total Solar Eclipse
Depending on the location on Earth, there is a Total Solar Eclipse on July 21st or 22nd. Visible from Eastern China, Japan and the South Western Pacific, the eclipse crosses the International Date Line.

Mercury is visible the first few days of July in the morning hours. By July 4th, Mercury disappears into the glare of the sunrise and reappears on the evening side of the Sun around July 24th. After July 24th Mercury continues to move in better position for viewing until August 24th when Mercury reaches its Greatest Eastern Elongation.

Mercury begins the month in the constellation Taurus (The Bull), and on July 3rd, crosses into the constellation Gemini (The Twins). Then behind the glare of the Sun, Mercury crosses Gemini until July 16th when it moves into Cancer (The Crab), and after Mercury re-emerges in the evening, it moves finally into the constellation Leo (The Lion) on July 26, where it will spend the rest of July.
Venus is visible as the Morning Star for the entire month of July. Venus begins this month in the constellation Taurus (The Bull) until the end of the month. On July 29 Venus crosses into the constellation Orion (The Hunter) where it will stay until the last few minutes of July and it crosses into the constellation Gemini (The Twins).
Mars can be observed in the morning hours above Venus in July. At the beginning of the month Mars is only about 4° above Venus and as the month progresses Venus continues to move further away until the end of the month they are about 16° apart.
