President’s Report

Wison

By Chris Wilson, CASCA president
(Cassiopeia – Hivers/Winter 2015)

Hi, everyone,

Well, the end of term is in sight but like many of you, I am still swamped with marking and student meetings. So this will again be a short report noting a few important highlights.

Our next annual meeting will be held in Winnipeg, Manitoba. The graduate student workshop will be on May 30th, 2016 with the CASCA meeting itself May 31st – June 2nd, 2016. The meeting will be held at the historic Fort Garry Hotel, located in the heart of Winnipeg, within easy walking distance of many attractions such as The Forks and the Canadian Museum for Human Rights. More information is available on the meeting web site. Registration will open in January.

Work on the report from the Mid-Term Review panel is well underway; the committee estimates that roughly 90% of the document has been written. The panel is holding weekly telecons and I think the report is converging quite quickly. While there is a certain amount of polishing that will be needed, the panel is working to have the full report completed early in the new year.

I am sure that many of you continue to follow the latest news on the TMT from Hawai`i. In early December, the Hawai`i Supreme Court invalidated the Conservation District Use Permit issued by the Board of Land and Natural Resources (BLNR) to the University of Hawaii – Hilo to build TMT on Maunakea. This means that TMT will need to apply for a new permit in Hawai`i in order to build on the Maunakea site, with September 2016 the earliest possible date on which a new permit could be obtained. We continue to monitor the situation and will share information as it becomes available and can be made public.

Members of the ACURA Advisory Committee on the SKA helped to organize a workshop on “Canada and the SKA” that was held at the University of Toronto December 10-11, 2015. The meeting was an opportunity for the Canadian community to assess its main interests and activities for the SKA, and to identify areas for synergy and coordination. There was good turnout by astronomers from a number of Canadian universities and NRC-Herzberg, as well as participation by a number of potential industrial partners and a number of international astronomers as well. If you missed the workshop, the talks are expected to be made available soon on the conference web site.

The CASCA Board held two meetings this fall, a short one in October and our longer mid-year meeting in December. These meetings are held electronically to save time and travel costs. We also discuss issues as they arise via email and igloo (a community forum software). The new Diversity and Inclusivity Committee has been established; its first chair is Dr. Brenda Matthews from NRC-Herzberg and you can find the membership and terms of reference on the CASCA web site. Another task at this time of year is identifying new members to serve on CASCA committees: a big thank you to everyone who has agreed to serve our community in this way!

One of the major areas of discussion over the past 18 months has been the Westar trust and the Westar Lectureship. In my previous report, I described how the Board had committed a portion of the income from the Westar funds to support the Discover the Universe Initiative. A big focus over the next 6 months will be working to re-establish the Westar Lectureship series. The Westar lectures occurred quite regularly in the 2000s but as far as I can tell was overtaken in 2009 by the International Year of Astronomy and never restarted. The CASCA Board is working with our EPO committee and Discover the Universe to implement a new model that combines a Westar lecture by an astronomer with hands-on teacher training activities offered by Discover the Universe. Expect to see a call for volunteers in early 2016.

Happy holidays!

JWST Early Release Science Program: A Survey to Gauge Community Interests

The James Webb Space Telescope (JWST) is scheduled for launch in October 2018, and the first call for proposals will be released in 2017. The Space Telescope Science Institute, following the recommendations of the JWST Advisory Committee (http://www.stsci.edu/jwst/advisory-committee/JSTAC-Recommendations_ERS_CF.pdf), is now defining the parameters for an Early Release Science (ERS) program.

The primary objective of the ERS program is to provide community access to a broad suite of JWST science observations as early as possible in Cycle 1. The observing programs will be chosen by peer review to provide representative datasets and to address technical challenges related to the major instrumental modes available on JWST. ERS observations are expected to seed initial discovery and to inform Cycle 2 proposals, which will be submitted just months after the start of Cycle 1.

We are gathering community input to inform our preparations for the program and invite your participation in our brief survey at http://goo.gl/forms/lR0rHG4H4o. The survey will be open until 15 January 2016 and consists of four pages; it should take 10-15 minutes to complete.

More information on the general framework and timeline for the ERS program can be found on the ERS webpage (http://www.stsci.edu/jwst/science/ers). Questions and/or comments are welcome via email (jwst_ers [at] stsci.edu).
