Attached the latest Callisto status report. Pages 1-2 success from Callisto in Kigali, Rwanda. They got their first light this week. *Congratulations and welcome on the e-Callisto network.*

Pages 2-10 we see one of the first observations with the new 8 channel filter bank FFT-spectrometer M9703A, designed together with Keysight (ex. Agilent), FHNW, University of Berne (IAP) and ETH. The spectrometer has a very high resolution in time (>= 20 ms) and frequency (48.8 KHz) and a high dynamic range. The spectrometer provides 8 channels times 400 MHz or 4 channels times 800 MHz bandwidth. Spectrum readout as power, complex power, cross-power and many other products with 16384 frequency bins.

For comparison on the following pages all Callisto instruments which provided their data files from the same event NOAA 20141016events.txt (click here)

In all plots an average background was subtracted!

By the way this burst is ideal to determine the SEFD = S(Y-1) to qualify the instrument sensitivty. Explanations SEFD, Can be seen from the lecture

You may have noticed that the 26^th General Assembly of the International Union of Geodesy and Geophysics (IUGG) is fast approaching. This event will be held in Prague, Czech Republic, from the 22nd of June to the 2nd of July 2015. As chairman of the Local Organising Committee IUGG 2015, and on behalf of the entire Czech Geosciences community, I cordially invite you to attend this once-in-a-lifetime scientific and social event.

IUGG holds its general assembly every four years and Prague is proud to be the only city to host this event for the second time. In 1927, Prague hosted the third IUGG General Assembly of 300 participants.

Since then, the IUGG has made admirable breakthroughs in all aspects of Earth Sciences. Currently, IUGG is a composite of eight semi-autonomous associations covering various physical, chemical, mathematical, and environmental disciplines. Concurrently, Prague has flourished in the last two decades and become an affordable destination with high quality services. Prague ranks the 5th most visited city in Europe with over 4 million tourists annually. The Prague Congress Centre, located near the city centre, offers an optimal solution for this event and presents an ideal site for the 5000+ expected conference participants from around the world.

While attending scientific lectures and partaking in discussions with your colleagues in Prague, you can benefit from this unique city, which is recognised for its cultural and culinary selection. We are here to make your stay in Prague unforgettable through a wide selection of scientific trips and guided tours. The Science Program Committee has prepared the road map for the scientific program and determined its basic features. At present, union symposia are well defined in terms of conveners. Their descriptions are available here. Lists of solicited speakers of individual symposia are in an advanced phase of preparation. A complete scientific program will be ready in July when the registration and abstract submission tools will also be available.

Please mark IUGG 2015 in your calendars - the scientific meeting of the upcoming year.

I would like to share the words of Albert Einstein, a resident of Prague between 1911 and 1912. “Besides, the city of Prague is wonderful, that beautiful that this city alone would already prove of value for a longer journey.”

We look forward to making your trip to Prague in 2015 a great success!
