WIYN Observatory

WIYN Status - Semester 2017A Proposer Information

NOAO Time on WIYN in Semester 2017A

NOAO will continue to offer access to WIYN and its instruments to the national community in 2017A, albeit with a focus on research programs that are related to exoplanets. Interested observers should consult the NOAO WIYN 2017A Observing Proposal Call for details. This does not apply to people applying for time through WIYN's university partners.

Instrument availability in 2017A

There are several key things to note about the availability of 3.5-m instruments in 2017A:

Remote Observing

Remote observing at WIYN is now available to all qualified observers (see the remote observing policies). Those wishing to observe remotely with ODI must do so from a pre-approved (and tested) workstation. More information can be found on the WIYN Remote Observing page.

WIYN 0.9m Status

In October of 2013, the WIYN 0.9m observatory started commissioning and initial operations with the Half Degree Imager (HDI). The 0.9m consortium is currently offering nights with HDI to the community as shared risk, through proposals submitted to NOAO. S2KB is the backup instrument if HDI becomes unavailable.
