Repairs to Jabba at Carnarvon in 2016 March

Hale, Steven J. (2016) Repairs to Jabba at Carnarvon in 2016 March. Technical Report. Birmingham Solar Oscillations Network.



The signal to noise performance of spectrometer-J (Jabba) has been deteriorating since it was installed in 2009 July. The fault was identified as being a failed Schott KG4 short-pass infra-red filter. Since KG4 has been discontinued and no spares are available, it was decided to simply remove the filter and run with only the Schott RG9 coarse red pre-filter installed. Additional work identified a failed rain detector which was removed and returned to Birmingham, with a replacement to be shipped out as soon as possible. The batteries in the UPS were also replaced.
