THE 1.6-M NEW SOLAR TELESCOPE (NST)

11/04/2015 Asia-Pacific Solar Physics Meeting

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).

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

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.

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.
