2019 Thomas Metcalf SPD Travel Awards – FINAL CALL for Applications from Meeting Organizers
Marc DeRosa
01 Mar 2019
The Solar Physics Division (SPD) announces the FINAL CALL for the Thomas Metcalf SPD Travel Award Program for 2019. The Thomas Metcalf Travel Fund was established in 2007 with generous contributions from his family and many others to help early-career scientists attend meetings relevant to solar physics. For this year, two or three meetings will be selected by the Metcalf Travel Award Committee (MTAC) on the basis of brief applications from Meeting Organizers. The total amount available this year is expected to be about $10,000.

Briefly, the procedure is as follows. First, an application is submitted by Meeting Organizers to the MTAC. If selected, Meeting Organizers will then seek out qualified early-career scientists who can make a significant contribution to their meeting. Awardees (hereafter, Metcalf Lecturers) will be chosen by Meeting Organizers based on their potential for future contributions to the field of solar physics and relevance to the topic of the meeting. (Prospective Metcalf Lecturers should apply directly to the Meeting Organizers, and not to the MTAC. The MTAC, however, will verify the eligibility of each awardee.)

Organizers of meetings relevant to solar physics taking place before 1 April 2020 are encouraged to submit an application to Marc DeRosa ( for consideration by the full MTAC. Applications should be no more than three pages, and must be received by 20 March 2019. Check the application guidelines for additional details.

Metcalf Lecturers for 2019 must have received their Ph.D. no earlier than January 2015 or be a student within one year of completing their Ph.D. Awardees must be a member of the SPD (affiliate membership is OK) and not already have been a Metcalf Lecturer previously. Awardees must present their work at the meeting, and after the meeting they must submit a one-page report describing their contribution. Grants are provided directly to the Metcalf Lecturers by the Treasurer of the SPD upon receipt of their report by the MTAC.

For additional information about the program, please consult the program rules or contact Marc DeRosa (

ESA – Invites Input for the Long-term Planning of the ESA Science Program for 2035–2050.
Jorrit Leenaarts
04 Mar 2019
I would like to draw the attention of the solar community to the start of ESA’s long term science planning for the period 2035 – 2050, called Voyage 2050. It is described as follows on ESA’s homepage:

“The next planning cycle of the ESA Science Programme, Voyage 2050, is now underway. In keeping with the bottom-up, peer-reviewed nature of the Science Programme, the definition of the next plan relies on open community input and on broad peer review. The community input will be gathered through the Call for White Papers, while the peer review of this input will take place through a two-tiered committee structure, with a Senior Committee of 13 European scientists supported by a number of Topical Teams. Scientists interested in participating in peer review process are invited to respond to the Call for Membership of the Topical Teams.”

More information on how to write a White Paper and how to apply to be member of a Topical Team can be found on Any scientist (also from non-ESA member states) can be an author on a White Paper. Membership of topical teams is restricted to scientific test from ESA member states. Lead authors on White Papers cannot be a member of a Topical Team.

While the Senior Committee can add science topics to the Voyage 2050 plan if it feels certain topics are not sufficiently covered by the White Papers, the plan is mainly driven by interest from the science community. I therefore urge the solar community to submit White Papers and apply for topical teams.

IRSOL, Switzerland – Postdoc Position in Solar Physics: Deadline Postponed, 31 March 2019)
Michele Bianda
14 Mar 2019
Istituto Ricerche Solari Locarno (IRSOL), located in the Italian-speaking southern part of Switzerland, is a solar research institute that operates a   facility   optimized for high-precision imaging spectro-polarimetry (see The Institute is associated with the Università della Svizzera italiana (USI). IRSOL is offering a postdoc position in the field of instrumental development and solar physics, financed by the H2020 project SOLARNET-2. High-sensitivity instruments, capable of measuring very small polarization signals, have been used for many years. Although these instruments can reach sensitivities down to 10-5, the absolute value of the measured signals is generally limited to an accuracy of 10-3 at most due to the spurious signals induced by their various optical components, starting from the telescope main mirror down to the detector.

The possibility of measuring the absolute value of the polarization with a very high precision would represent a key achievement in the field of solar spectro-polarimetry. In particular, it would represent a major breakthrough in the measurement of spectral line polarization signals. Indeed, their amplitude and shape could be precisely determined without the uncertainties that are necessarily introduced when the overall polarization scale of the observation is adjusted on the basis of theoretical values of the continuum polarization level, as it is presently done.
At IRSOL, for measuring the continuum polarization with a very high absolute precision, a new method was used that permits to achieve excellent results combining low frequency modulation, obtained rotating a retarder located in front of the telescope, and high frequency modulation performed with a high   sensitivity polarimeter located after the telescope.

The postdoc is expected to improve this method, extending its applicability to a wide variety of polarization measurements where high precision is required in its absolute value. Furthermore, the application of this technique at high   spatial resolution, using large aperture solar telescopes, should be studied. In particular, the postdoc will have the following responsibilities:

Position requirements: The candidate should preferably have a background in solar physics with experience in polarimetry and good practical knowledge in instrumental
development. The capability to conduct independent work and good communication skills are expected.

The gross annual salary for the first year will be CHF 80,000 (the annual
salary will gradually increase).

The expected starting date is the beginning of May 2019 (postponement negotiable). It is a two year position with the possibility of applying for renewal.

How to apply:
Applications must be sent via e-mail to and must include the following documentation:
