5. The Night Sky Friday, April 27 · Look for Pollux and Castor, the not-quite-twin stars of Gemini, upper right of the Moon this evening. Lower left of the Moon shines Procyon. · This evening a 9.7-magnitude star in Virgo will be occulted by the small asteroid 1030 Vitja along a path from the New York City area though the northern Great Lakes. The occultation will happen within a few minutes of 9:57 p.m. EDT and will last for up to 6 seconds. Maps and details. Saturday, April 28 · Evenings this week sport three planet-and-star pairs. High in the south, Mars shines with Regulus to its right at dusk, lower right later. Down in the southeast, Saturn shines with Spica to its lower right. Both these pairs are now about 5° wide. Meanwhile in the west, dazzling Venus is approaching much fainter Beta Tauri (El Nath) above it. Tonight Venus and Beta Tauri are 3.5° apart. By Saturday May 5th their separation is just 0.9°. Sunday, April 29 · The Moon shines near the Leo-Cancer border, forming a roughly straight line with, running to its left or upper left: 4th- magnitude Omicron Leonis, 1st-magnitude Regulus, and zero-magnitude Mars. Monday, April 30 · The Moon shines below Mars, Regulus, and Gamma Leonis (Algieba) this evening, as shown here. · Venus is at its "greatest illuminated extent" — showing the most sunlit apparent area (in square arcseconds) that it's going to this apparition.
