VISIR News

• IMPORTANT. February 20, 2013: Due to problems with the new Raytheon detectors, VISIR will not be available for regular observations during P91 & P92.
• October 25, 2012: Due to out-of-specifications properties of the new detectors, VISIR is not available for regular observations during P90. Most likely this will be the case for the entire period.
• September 4, 2012: The P90 User manual applies also for P91 phase-I preparation.
• August 17, 2012: An updated version of the P90 User Manual is available.
• August 17, 2012: Problems during the first re-commissioning run did not allow to meet the sensitivity expectations. A second re-commissioning is planned for the end of October 2012. Regular science operations with VISIR are expected to resume at the begining of November 2012.
• December 8, 2011: The VISIR upgrade is scheduled between May-September 2012. Thus, approved P89 programs will cluster either in the month of April or in the last 2 weeks of September 2012.
