NISP engineering team is completing EVT camera deployment and the preventive maintenance activities at GONG/Teide station in Tenerife, Canary Islands. The team also inspected and cleaned H-alpha filter optics. Both field lenses had copious amounts of oil deposits. The lenses were cleaned which drastically improved the TD image, no more bright sky around the solar image, prominences are more easily seen now (see H-alpha images before/left and after/right its cleaning).
NSO-CU crew were on site this week filming the work of the engineering
team and interviewing IAC/Teide Observatory staff in preparation for
30th anniversary of GONG operations public outreach events.
NISP data center and scientific staff are preparing to start data vetting and camera acceptance activities once GONG/TD is back in operations.
