PC pages

These web pages provide information about the current proposal assessment process for observing time at the Westerbork Synthesis Radio Telescope (WSRT). Information on Dutch observing time on the JCMT, WHT and INT telescopes can be found here.


First time users of the web proposal submission tool, NorthStar, should take note of this Instruction Link.
Instructions on justification file format must be strictly observed. The WSRT web proposal tool is accessed at http://wsrt.astron.nl/proposal.

Proposal deadline

There are no current deadlines to submit proposals for the WSRT, due to installation and commissioning of the APERTI System.

Urgent and interim proposals for the WSRT can not be accepted either, for the time being.


The latest deadline for supplemental WSRT MFFE-proposals was on Monday 6 October 2014 at 12:00 UT (14:00 CEST).

For more details please see the latest call for proposals. Requests for observations of extremely important transient or non-predicted events and other urgent and interim proposals can be submitted at any time via the web proposal tool to the Director of the Radio Observatory at ASTRON. Requests for short “filler-type” observations can also be submitted at any time. See the Policy for WSRT Observing Time.
