See the moon shine near Mercury before dawn on Monday


Look to the east-northeastern horizon before dawn on Monday (June 27) to see the moon wrap up its monthly tour of the morning plants with Mercury. 

“The silver sliver of the old moon‘s crescent will shine several finger widths to the upper left (or 3.5 degrees to the celestial north) of the bright dot of Mercury,” writes Chris Vaughan, amateur astronomer with SkySafari Software who oversees’s Night Sky calendar.
