Full Moon
Apr 19 all-day

April 19 – Full Moon. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 11:12 UTC. This full moon was known by early Native American tribes as the Full Pink Moon because it marked the appearance of the moss pink or wild ground phlox which is one of the first spring flowers. This moon has also been known as the Sprouting Grass Moon; the Growing Moon; and the Egg Moon. Many coastal tribes called it the Full Fish Moon because this was the time that the shad swam upstream to spawn.

Lyrids Meteor Shower
Apr 22 – Apr 23 all-day

April 22-23 – Lyrids Meteor Shower. The Lyrids is an average shower usually producing about 20 meteors per hour at its peak. It is produced by dust particles left behind by comet C/1861 G1 Thatcher which was discovered in 1861. The shower runs annually from April 16-25. It peaks this year on the night of the night of the 22nd and morning of the 23rd. These meteors can sometimes produce bright dust trails that last for several seconds. The waning gibbous moon will block out many of the fainter meteors this year but if you are patient you should still be able to catch a few of the brightest ones. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Lyra but can appear anywhere in the sky.

Eta Aquarids Meteor Shower
May 6 – May 7 all-day

In the Northern Hemisphere the rate can reach about 30 meteors per hour. It is produced by dust particles left behind by comet Halley which has known and observed since ancient times. The shower runs annually from April 19 to May 28. It peaks this year on the night of May 6 and the morning of the May 7. The thin crescent moon will set early in the evening leaving dark skies for what should be a good show. Best viewing will be from a dark location after midnight.

Full Moon & Blue Moon
May 18 all-day

May 18 – Full Moon & Blue Moon. The Moon will be located on the opposite side of the Earth as the Sun and its face will be will be fully illuminated. This phase occurs at 21:11 UTC. This full moon was known by early Native American tribes as the Full Flower Moon because this was the time of year when spring flowers appeared in abundance. This moon has also been known as the Full Corn Planting Moon and the Milk Moon. Since this is the third of four full moons in this season it is known as a blue moon. This rare calendar event only happens once every few years giving rise to the term “once in a blue moon.” There are normally only three full moons in each season of the year. But since full moons occur every 29.53 days occasionally a season will contain 4 full moons. The extra full moon of the season is known as a blue moon. Blue moons occur on average once every 2.7 years.

It will be brighter than any other time of the year and will be visible all night long. This is the best time to view and photograph Jupiter and its moons. A medium-sized telescope should be able to show you some of the details in Jupiter’s cloud bands. A good pair of binoculars should allow you to see Jupiter’s four largest moons appearing as bright dots on either side of the planet.
