Since May 27th 2008 a new host site is operational. Welcome on board of e-Callisto network Frédérice Clette and Christophé Marque of ROB (Royal Observatory of Belgium) with their station in Humain.

Actual status of present host sites:
Spectrometer Ooty/India operational
Spectrometer Gauribidanur/India operational
Spectrometer Badary/Irkustk/Russian Federation operational
Spectrometer CINESPA/Costa Rica operational
Spectrometer Unam, Mexico operational
Spectrometer Switzerland 3 spectrometers (Bleien, Zurich and Freienbach) operational
Spectrometer KASI Daejeon South Korea 2 spectrometers operational
Spectrometer ROB/Humain operational
Spectrometer IHY2007 mobile-exhibition Europe operational (no data, just some visualization)
In total, 12 spectrometers worldwide are currently operational

•	New requests from Indonesia, Brazil and Ecuador are now being discussed
•	A preliminary request from Cuba also under discussion
•	Different calibration methods still under discussion any idea/recommendation very welcome
•	A new application within CRAF was proposed (A. Jessner MPIfR): continuous rfi-monitoring
•	A new application was proposed in Belgium: monitoring of meteor-scattering below 150MHz
•	Callisto from NRAO in Green Bank was sent back because it was not used for scientific work. Most components were recycled for two new spectrometers
•	Akure, Nigeria was rejected due to overlapping longitude
•	Ahmedabad, India was also rejected due to overlapping longitude
•	Delhi, India was also rejected due to overlapping longitude
•	Malaysia was also rejected due to overlapping longitude
•	Nobeyama Japan is not interested in Callisto
•	Learmonth Australia unfortunately is not interested in Callisto at all
•	The original dual-receiver Callisto in Ooty has been successfully replaced by two new e-Callistos. Thus, all spectrometers have now identical hardware configuration (programmable gain).
•	A paper has recently been published: Bull. Astr. Soc. India (0000) 00, 000-000,  C. Monstein, R. Ramesh, C. Kathiravan, Radio spectrum measurement at the Gauribidanur observatory
•	Updated spectral measurements can be found here: http://www.astro.phys.ethz.ch/instrument/callisto/RFSPEC2/spectrum2.htm
•	We still have 5 tested Callistos on stock and we have components available to manufacture 10 additional spectrometers. After that, it will be not possible to manufacture Callistos, because there are no more analog tuners available at Philips.
•	DiRaC software and website are not working at the moment due to changes in server configuration and due to several software updates. Since our institute is now moving to another location we will need a few weeks to get operational again. If there should be any flare recorded in the meantime, we will collect them ‘manually’ using ftp or sftp.
