Venus and Jupiter during the day 2022-01-22

Venus and Jupiter during the day 2022-01-22 A planet captured before and after lunch. After the inner conjunction, Venus was about 10 ° to the west of the Sun and became a crescent with good contrast without being disturbed by sunlight. Jupiter is in the sky 30 ° east of the Sun, and although it is a faint image with a telescope, you can see the striped feature of Jupiter itself. There was a Great Red Spot (GRS) around the lower left of the Jupiter image, but it was not visible visually. The images of Venus and Jupiter have the same magnification, so you can see the difference in apparent size.
