Auroral Map 19580211

11 February 1958 Synoptic Auroral Map


By early 1958, under the auspices of the International Geophysical Year, the National Research Council had compiled a list of amateur contributors to an auroral research program. The period of maximum solar activity in an 11-year cycle had peaked in late 1957, and Helen Sawyer Hogg reported in her Toronto Star column of June 7th, 1958 that the relative sunspot number for December 24th and 25th was 355. This was the highest value ever observed, exceeding the value of 353 on May 17th 1778.

My Top Astronomical Experience of 2011: Exploring the Far-Southern Skies

Southern SkiesChoosing my top astronomical experience for 2011 is easy for me, as my wife and I spent 5 weeks in New Zealand, travelling all over, often staying in places away from large cities. The view we had of the far-southern skies almost defies description.

My Top Astronomical Experience of 2011 - Completed Life List

(Posted by MMcBride)

Asking an amateur astronomer to express in words their top astronomical event is akin to pointing out the astronomical singularity of the big bang, where and precisely when did it occur across this immensely beautiful universe? Really does it matter – isn’t it just important to know that it did? I had a year full of top astronomical events, firsts and bests moments ever; is that not the beauty of our hobby, one that is full of challenges, opportunities, personal discoveries and triumphs? The awesomeness of our universe begs us not to expect anything less from this living, breathing and ever changing soup of creation than the awe and wonder we find just simply being out amongst the stars. Still, I must choose between the moments but how, but, what? Glad the year was already picked for us, as I would be stuck in an endless loop of emotional wonder and amazement with no escape.

Venus visits the evening sky.

Venus is the focus in the Western sky in the coming months and shines brightly.  It is very close in size to our own planet but the atmosphere of Venus would not be kind to life of any kind.

My Top Astronomical Experience of 2011 - Epsilon Aurigae

I did manage to get an Astrotrac tracking mount for my birthday however and I stumbled upon the Citizen Sky project to observe the eclipse of Epsilon Aurigae.
