On June 6th, 00:26, the longitude of the sun is 75º, which marks the ninth solar term of the year—Grain in Ear. Around this solar term, as wheat becomes ripe for harvest, farmers are in a rush for harvesting wheat and planting rice or corn. Grain in Ear is followed by summer time, when most flowers begin to wither away。
The sun travels in Taurus. Currently, solar activities are increasing. On the front surface of the Sun, 5 groups of sunspots can be observed through a telescope with a light filter device.
On June 14th, 19:52, the moon becomes a full moon. The distance between this “supermoon” and the Earth is less than 360,000 kilometres. After sunset, the full moon rises from the south-eastern sky and shines brilliantly all night。
Mercury travels in prograde motion in Taurus. It will reach its greatest western elongation on June 16th at 23:00. Its angular distance to the Sun is 23º and can be observed with a telescope before dawn.
Venus travels in prograde motion from Aries to Taurus. On June 11th, it is at conjunction with Uranus. In the low eastern sky before sunrise, extremely bright Venus can be seen with naked eyes, while it requires a telescope to find Uranus.
After passing through Cetus shortly, Mars continues to travel in prograde motion in Pisces. It rises around 2 o’clock in the morning, and can be found in the south-eastern sky before sunrise.
Jupiter travels in prograde motion in Pisces. It rises around 1:30 in the morning and is located in the south-east sky before dawn.
Saturn travels in retrograde motion in Capricornus. Before dawn, the third largest moon of Saturn, Iapetus, enters the shadow of Saturn. The eclipse of Iapetus begins at 00:09 and ends at 03:38, which can be observed with a telescope. Such event as seen from the Earth takes place about every 15 years.
