  1. Big Bear Solar Observatory –The NST Philip R. Goode Big Bear Solar Observatory New Jersey Institute of Technology

  2. Background • BBSO 65-cm telescope 1 of 2 hi-res in US - Different mission than DST - Long tradition of observing campaigns -Essential for studies of space weather • Transferred from Caltech to NJIT 5 years ago - Expanded NJIT group to 4 tenure-track faculty - 10 PhD students (including 3 women) - 2 graduated last year - 175+ publications (bluebooks) Big Bear Solar Observatory

  3. BBSO’s Place Under the Sun • Upgraded instrumentation (2nd generation) - New polarimeters (IR + VIS) - Real-time speckle reconstruction - AO • By 2006: Ready to solve many space weather problems - SDO, STEREO and Solar-B in space - 0.5 m telescope in space - 1.5 m telescope in Europe (GREGOR) - No ATST until 2010 Big Bear Solar Observatory

  4. The 1.6 m Telescope – the NST (New Solar Telescope) • 2006 - first light • Replaces the 65 cm telescope • Open, off-axis & feeds new instrument-ation • Gives BBSO a future & students to use ATST Big Bear Solar Observatory

  5. Schematic of the NST • Same fork & pedestal • Cost sim. to GREGOR • Stray light reduction • No central obscuration • Heat stop out of optical path • Retractable dome Big Bear Solar Observatory

  6. A BBSO/UHawaii Collaboration in NSF-MRI • NJIT to invest $1.3M & MRI request is $1.8M - highly leveraged • AFOSR –DURIP (hopefully) for figuring blank and mirror cell. • BBSO/UH collaborate on mechanical, thermal and computer control • UH interest in combined NST & SOLAR-C observations and a larger coronagraph downstream • UA Mirror Lab involvement for primary - 20/20 project and NST primary • Members of design team coming into place • Liaison with NSO/ATST team • Work with GREGOR team on thermal issues • What if BBSO is chosen as ATST site ? Big Bear Solar Observatory

  7. NST Science • High-res, high-cadence studies of solar flares • Structure/evolution of magnetic fields in flaring active regions • Dynamics of kG flux tubes • Magneto-convection in sunspots • Heating of the upper atmosphere - intra-network fields Big Bear Solar Observatory

  8. The ATST • NST keeps US solar on a par with Europe • Gives our field a future for a generation • NST remains important for campaigns and education Big Bear Solar Observatory

  9. New Jersey Institute of Technology Public Research University • 8,200 students in 76 programs (Bachelor/PhD) • College of Science and Liberal Arts • Physics Department • Center for Solar Research • Big Bear Solar Observatory • Owens Valley Solar Array • NJIT’s remote research facilities Big Bear Solar Observatory
