Waiting for the Antenna Cable

State of the Project

Software Test

First measurement without Antenna

Waiting for the antenna cable and for a fix desktop for callisto we installed the software and we maked a first measure just to test the component.

Intensity in time and frequency domain [45 - 870 MHz]

Callisto Hardware Test

Hardware test in Progress

Today we start with the test of the Callisto components.

This is the new Callisto Box, smaller then the prototype.

The Hardware, a normal PC with Callisto connected by Serial Port. (we use a usb adaptor)

The Antenna

The first step of building Callisto hardware is the setting up of the antenna. Taking advantage of the nice weather yesterday October the 5th we start the assembling of the antenna.

Callisto Arrives in Ireland

Callisto Arrives in Ireland

The coverage of Europe regarding the radio waves between 45 and 870 Mhz is limited. To help the survey in this spectral range a few callisto spectrometers were build. The main head of the project is at ETH Zurich radio observatory in Bleien (Switzerland). Now is in progress the assembling of callisto in Trinity College Dublin.

Solar Flares

Solar Flares

The dynamics of solar corona is still not understood and new phenomena are unveiled every year. The plasma emitting radio waves are little or not at all known.

Radio waves at meter and decimeter length, can be used as a diagnostic of the solar processes. They provide a first signature of five important events:

• Type I noise storms

Radio waves record unexplained emissions of solar active regions.

• Type II flare shocks

Energetic phenomen indicative of magnetohydrodynamic shocks in the low corona.

• Type III burst

Electron beams escaping as open magnetic lines field.

• Type IV events

Long lasting emission after large flares

• CMEs

Predictive potential of radio emission regarding CMEs heading towards Earth.

About Callisto

Callisto Solar Radio Spectrometer

Callisto is a dual-channel frequency-agile receiver. The total bandwidth is 825 MHz, from 45 to 870 MHz in steps of 62.5 KHz with potentially 13120 channels. This high resolution helps to avoid channels with terrestrial interference.
