Wandering through the realms of the cosmos, pondering its huge vastness

Skywatching Highlights: June 2011

This month’s skywatching highlights:

  • June Solstice. The Sun reaches its most northerly point in the sky, the June solstice, on June 21 at 17:16 Universal Time (UT).  This marks the beginning of summer in the northern hemisphere and winter in the south.
  • Partial Solar Eclipse.  Visible from the Arctic, Siberia, and parts of Iceland on June 1.  The eclipse peaks at 21:16 Universal Time.
  • Total Lunar Eclipse.  Completely visible on June 15 from South Africa and western Australia, this long and deep eclipse is the first of 2011.  The eclipse peaks at 21:12 UT.
  • Boötids Meteor Shower. Peaks on or about June 27 near midnight, this unpredictable meteor shower has shown up to 100 meteors an hour.  Or it could be a dud.  The Moon isn’t a factor this year, so take a look and see what happens.  The radiant is just off the peak of Boötes, though you can see meteors anywhere in the northern sky.





Partial Solar Eclipse – This will not be visible in the Philippines. The eclipse will begin at exactly 3:25 a.m. (Philippine Standard Time). It will be visible in Eastern Asia, northern N. America, the N. tip of Scandinavia, Greenland and Iceland.
