Here are a few notable astronomical phenomena happening this month, plus upcoming GRAAA events.
π On June 17 the Moon will pass in front of Venus, creating a lunar occultation visible during the afternoon from Grand Rapids. It will begin with the disappearance of Venus behind the Moon at 3:29pm ET and its reappearance will occur at 4:53pm ET. EXTREME CAUTION IS NECESSARY when pointing binoculars or telescopes at the sky when the Sun is above the horizon.
π The June solstice on the 21st marks the first day of summer for those of us in the northern hemisphere. It will be the longest day of the year, and the day when the Sun's annual journey through the constellations of the zodiac carries it to its most northerly point in the sky. The summer solstice actually happens at one shared instant for the entire planet. In Coordinated Universal Time it is Sunday June 21 at 2:24 UTC, but for those of us in US Eastern Time that will happen at 10:24pm the night before. But the calendar headline still belongs to the 21st, which is the date that most almanacs and news outlets will use to mark the first day of summer.
π The June Bootid meteor shower will be active from June 22 to July 2, producing its peak rate of meteors around June 27. Seen from Grand Rapids the radiant point is circumpolar, so it will always be above the horizon and the meteor shower will be active all night. It is likely to produce its best displays soon after dusk, when the radiant point is still as high as possible in the sky.
π Public Night season is in full swing, and this month they will take place on June 6 and June 20. We will also welcome back the first of three Riverside Raconteurs storytelling events on June 26, and will be hosting our annual StarBeQue picnic for GRAAA members on June 27.
