A Lunar Dance with Venus: June 17, 2026

On June 17, 2026, the Moon passed directly in front of Venus in a rare lunar occultation. This event was visible across the contiguous United States, southern Canada, northern Mexico, and parts of the Caribbean and northeastern South America. The occultation occurred at approximately 16:40 EDT (20:40 UTC).

  • Observation Conditions: For observers in northeastern South America, the event occurred under dark skies after sunset. In the contiguous US, Caribbean, northern Mexico, and southern Canada, it was visible under daytime skies before sunset.
  • Celestial Details: The Moon was a thin waxing crescent (2-3 days old, 11%-14% illumination). Venus was 74% illuminated, shining at magnitude -4 with a 15" disk, and was 38 degrees from the Sun.
  • Observing Tips: While Venus is theoretically visible to the naked eye during the day, binoculars or a telescope were recommended. Observers were warned not to sweep the daytime sky with optics without knowing the Sun's exact location. One safe method was to place a telescope in the shadow of a building. Accurate ingress and egress times were available from the International Occultation Timing Association (IOTA).

This event was one of the final favorable occultations of Venus for the contiguous United States until 2029–2031.

A Busy June Sky

The occultation was just one highlight in a month packed with celestial events.

  • June 16: The Moon passed near Mercury.
  • June 17: Following the occultation, the Moon also occulted the open star cluster Messier 44 (the Beehive Cluster), visible from the southeastern US at dusk.
  • June 19: Venus transited just north of Messier 44.
  • June 7-9: A striking Venus-Jupiter conjunction occurred, with closest approach on June 9.
  • June 12: Mercury, Venus, and Jupiter aligned in the sky.
  • June 25-27: Mercury and Jupiter had a close approach.

Future Occultations of Venus in 2026

The June 17 event was the first of three lunar occultations of Venus in 2026. The others are scheduled for:

  • September 14, 2026 (visible from Southeast Asia)
  • November 7, 2026 (visible from southern South America)

Total Lunar Eclipse: March 3, 2026

A stunning total lunar eclipse occurred on March 3, 2026.

  • Duration: The entire event lasted 5 hours and 38 minutes (08:44 to 14:22 UTC), with totality lasting 58 minutes (11:04 to 12:02 UTC).
  • Visibility: The entire event was visible across the western half of North America, the Pacific region, Australia, New Zealand, and East Asia. Europe did not see the event.
  • Observation: No eye protection was required. This was the last total lunar eclipse visible over North America until June 25, 2029.

Seasonal Highlights: January to March 2026

Dark Sky Opportunities

New moons provided the darkest skies for stargazing:

  • January 18 at 2:52 p.m. EST
  • February 17 at 2:01 a.m. EST

Planetary Visibility (February & March)

  • Venus and Saturn: On February 19, a waxing crescent moon joined Saturn and Mercury after sunset. From March 7-8, Venus and Saturn were in a close conjunction, visible in the west after sunset. By March 25, Saturn transitioned to the pre-dawn sky.
  • Jupiter: Jupiter was prominent in the constellation Gemini. In mid-February, it was in a prime viewing position. By late February, it formed a rectangle with the moon and the stars Castor and Pollux.
  • Mercury: Mercury reached its highest evening altitude around February 20 and its greatest eastern elongation in mid-June.

Other Notable Events

  • February 2: Observers in the northeastern U.S. and eastern Canada could witness the Moon occult the star Regulus between 8:40 and 10:05 p.m. EST.
  • February 14 and first two weeks of March: The zodiacal light—a faint cone of light from sunlight scattering off dust—was visible towards the west after sunset from dark, rural skies.

Visible Constellations

Northern Hemisphere Winter Constellations

The winter hexagon dominated the night sky:

  • Orion (the Hunter): Identified by its three-star belt. The Orion Nebula (M42) was visible in Orion's sword.
  • Gemini (the Twins): Containing Castor and Pollux. Jupiter was located here.
  • Taurus (the Bull): Contains Aldebaran, the Hyades cluster, and the Pleiades (Seven Sisters).
  • Canis Minor & Canis Major: Home to Procyon and Sirius (the brightest star in the night sky), respectively.
  • Auriga (the Charioteer): Contains the star Capella.
  • Ursa Major (Big Dipper): Visible rising in the northeast after dark. Its pointer stars lead to Polaris.
Southern Hemisphere Prominences (from Santiago, Chile)
  • Argo Navis: The constellations Puppis, Carina, and Vela were prominent.
  • Canopus: The alpha star of Carina.
  • Crux (Southern Cross): Located approximately 13 degrees above the south-southeastern horizon and circumpolar.
  • Achernar: The end of the constellation Eridanus.
  • Orion: Visible in the northern part of the sky.

General Observing Tips

  • Allow your eyes 15 minutes to adapt to the dark for optimal viewing.
  • Use binoculars or telescopes for fainter objects like star clusters, nebulae, and planets during daytime.
  • Never look at the Sun directly or through any optical instrument without proper solar filters.
  • For daytime events, block the Sun with a building or other structure.
  • Magnitudes: Lower numbers indicate brighter objects.
