New addition to the lab! I bought Giovanni’s book via Amazon because it’s really epic. You can find freely downloadable, high-quality ebooks on his website: http://www.k100.biz/e-Books.html

Unfortunately, it’s a “niche-topic book” but every vintage Tektronix aficionado will appreciate it. As an owner of 400, 500, 2400, 7000 and 11000 Series Tektronix Oscilloscopes, this book is just a must-have. Well-spent 70 EUR!

Thank you Gianni, your books are truly well-written, informative, beautiful and inspiring.

Earth got hit by a Coronal Mass Ejection from our Sun’s activity region AR3664 yesterday. Polar lights were spectacularly visible in most parts of Germany. My friend Michael woke me up around 23:30 CEST (= 21:30 UT) and I immediately rushed to the outside. After taking few (bad) pictures with my smartphone, I moved back to my apartment and observed the natural spectacle from my balcony. We even saw the International Space Station passing over us – a very eventful evening.

The geomagnetic storm isn’t over yet, we might be able to observe further polar lights tonight! I’ll try to catch some photographs with my DSLR camera!

I will post more photos here.
