Night Sky

August 2007

I would like to acknowledge the generosity of Arthur Davis, whose monthly 'Sky Notes' hand-outs provide much of the information on this page.

Meteor Showers

The table below lists August's major showers. Visit Gary Kronk's page of August radiants for more information on this month's showers.

Note also that the night of the Perseid maximum this year (2007) will be clear due to a new moon (see below), making for near-ideal viewing conditions... as long as the weather holds!

The Sun

Solar Minimum passed last autumn (2006), so sunspot activity will gradually increase over the next five years or so.

It is always important to remember to never look directly at the Sun, especially not through binoculars or telescopes. Serious permanent damage can be done to your eyes. Always project an image of the Sun onto paper or card in order to make observations.
