The Summer Triangle
The days are getting very long at the moment, so you only get a few hours of observing time every night. Still there are always some interesting objects to observe, even with the naked eye. If you go outside around midnight you can see three bright stars high in the eastern sky, Deneb in Cygnus (the Swan), Vega in Lyra (the Harp) and Altair in Aquila (the Eagle).

Together these three bright stars form an asterism called the Summer Triangle. They range in brightness is from magnitude 0.03 to magnitude 1.25. Can you tell which one is the brightest and which one is the faintest? Maybe a good way to train your eyes and brains, learning to estimate the different magnitudes of stars.
Magnitude: the brightness of a star or any other celestial object. The higher the magnitude, the fainter the object.

On the map below (click to enlarge) you can see the Summer Triangle as a red triangle. Within the boundaries of this map lie two of my all time favorite binocular objects for 7x50 binoculars, the Cygnus star Cloud and the constellation Delphinus. In July/August I will try to observe these two brilliant objects. If I succeed, I will be back with some observing reports, finder charts etc. in the Deepsky Section (Binocular objects).

I hope you’re enjoying the planets venus, mercury, & saturn dancing around in the sky recently as much as I have. On the 29th (as I’m sure you already know) mars should be abnormally close to the moon, how neat is that?!

Loved your cresent moon pictures!

Hi Jenney,

I havn’t had a chance to observe the three planets yet, but tomorrow it should be clear skies around here, so I will have a go at them. I hope to capture them together one image, which of course will be posted in Clear Skies On Demand. Anyway, clear skies to all of you (and myself also a little bit).

I have run about 2,000 correlations of geophysical and solar system events with Planet-Star patterns. The events are terrestrial earthquakes, volcanoes, tornadoes, storms, power outages and more. Solar system events include
Solar tornado and Saturn storm.
Stars in the Ecliptic which are correlated with these events include Aldebaran, Alhena, Pollux, Regulus,
Spica and Antares. Extra-Ecliptic Stars include Deneb in Cygnus, Achernar in Eridani and Altair in Aquilae.
Please watch for Volcanic Eruption with Ash plume of 50,000 ft, power outage, electrical fire/explosion and electromagnetic disturbances, 7.0 earthquake, aviation accident and meridional jet stream flow on March 28 and April 17, 2008 - both dates plus or minus two days.
