4 THE 1.6-M NEW SOLAR TELESCOPE (NST) Telescope is performing flawlessly. The deformable mirrors of the AO system have been refigured for better performance. The instrumentation is functioning well, with some upgrades for 2015 (Wenda s talk). 4

5 BIG CHANGES FOR BIG BEAR Construction and commissioning is complete, and 2015 marks the first year of full science operations. Changes to enable science: Telescope allocation committee (TAC), to fully assign observing time to PIs based on scientific merit. Creation of Chief Scientist position (Haimin Wang), whose job is to coordinate science efforts. Addition of many scientists and students from Haimin s group. Weekly or bi-monthly assignment of duty scientists, who interact with PIs and observers every day to ensure a focus on science. Bi-monthly telecons to ensure regular communication between the observatory, its collaborators, and people on NJIT campus. Development of new instrumentation continues: Cyra, MCAO, new filters (red continuum, He D3). Guest observing bench. New and renewed collaborations 5

6 THE MAY-OCT 2015 OBSERVING SEASON The telescope allocation committee received 21 observing proposals covering 154 observing days. There were a number of spectacular seeing days, resulting in excellent data for science, especially in June. Here is a breakdown of the observing days, by group. Group/Instrument Dev. NJIT science proposals Korean science proposals Chinese science proposals Instrument development Engineering days Number of Days 65 days 19 days 40 days Cyra: 17 days, MCAO: 24 days 6 days 6

Dual-band spectra using dual CCD cameras Echelle grating with order-selecting filters 19

20 UPCOMING DEVELOPMENTS We submitted an expression of interest to the US National Solar Observatory for hosting the SOLIS instrument at BBSO. The NSO is now evaluating the bids (7 bidders). At least one group is interested in using our guest instrument bench (Craig DeForest SHAZAM), and is preparing a proposal to NSF. We intend to offer a small amount (2-4 weeks) of open observing time to the U.S. community during the upcoming observing season. We can expect that observing time will be over-subscribed in 2016, so quality and strategic importance of proposals will be ever more important. 20
