Herschel Announcement of Opportunity for Open Time (OT1) observations

Herschel Announcement of Opportunity for Open Time (OT1) observations

21 May 2010

The first in-flight Announcement of Opportunity (AO) for Open Time (OT1) observations with the Herschel Space Observatory has been issued. The OT1 call solicits proposals from the worldwide astronomical community and offers 6592 hours of Herschel observing time. The deadline for proposal submissions is: 22 July 2010 at 12:00 UT.

The full details and documentation of the Herschel OT1 AO can be retrieved from the dedicated pages at the Herschel Science Centre website:

The Herschel Space Observatory, launched on 14 May 2009, is the fourth cornerstone of ESA's Horizon 2000 Science Programme. It carries a 3.5 metre telescope and three science instruments: the Photodetector Array Camera and Spectrometer (PACS), for the wavelengths shortward of 200 µm, the Spectral and Photometric Imaging REceiver (SPIRE), for the longer wavelengths, and the very high resolution spectrometer Heterodyne Instrument for the Far Infrared (HIFI).

This Announcement of Opportunity (AO) is the first in-flight AO and it will be followed by another in about one year's time. The AO is divided into two parts. The first part was for the Guaranteed Time (GT1) programmes - this has already been conducted - while the second part refers to Open Time (OT1) programmes. Proposers from the worldwide astronomical community are welcome to respond to this call for Open Time proposals. All proposals will be subject to independent review by the Herschel Observing Time Allocation Committee (HOTAC).

Information about the already-approved observing programmes (GT and OT Key programmes, and GT1) is available on the Herschel Science Centre (HSC) website. Potential proposers are required to prepare and submit observing time proposals, in electronic form, by the deadline given below, according to the rules and using the Herschel observing planning tool HSpot, as described in the AO documentation package.

To allow Open Time proposers as much time for preparation as possible, two observation planning/HSpot workshops will be held in parallel from 3 to 4 June 2010, with one organised by the HSC at ESAC in Madrid, and one by the NHSC in Pasadena, USA.

The key milestones for the Herschel OT1 AO are:

20 May 2010: Issue of the Herschel OT1 AO.
3-4 June 2010: Observation planning/HSpot workshops at HSC (ESAC, Spain) and NHSC (IPAC, USA).
