WIYN Status - Semester 2015A Proposer Information


pODI is scheduled for regular observing through mid-November, 2014. After this point, pending final approvals, pODI is expected to be removed for an upgrade. This instrument is not likely to be available for most of semester 2015A; in fact it is not being offered as part of the NOAO call for proposals. There may be a small amount of early shared risk science time with the upgraded instrument available for the university partners in July, 2015. If NOAO continues to be a partner in WIYN, the instrument is expected to be available to the national community starting again in semester 2015B.

Other instrument availability in 2015A

There are several key things to note about the availability of the other 3.5-m instruments in 2015A:

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.
