Nordic Optical Telescope: OPTICON Call for proposals

The OPTICON common call for EU supported access to telescopes in semester 2019B (1 October 2019 – 1 April 2020) is open. It will close on 28 February 2019 at 23.59UT exactly.

The NORDIC OPTICAL TELESCOPE offers a total of 25 nights per semester.

For the details of the announcement, see:

https://www.astro-opticon.org/h2020/tna/call/call-2019b.html

ALL non-Nordic and non-Spanish proposals for the Nordic Optical Telescope MUST be submitted through the OPTICON common proposal and evaluation system.

We would like to *emphasize* that apart from regular visitor mode, the NOT also offers (queue) service mode observing and provides a wide range of options for flexible scheduling through Target-of-Opportunity programs and/or monitoring programs on any time-scale (from hours, to days, to weeks, to months, to years).

*We note that*

– A set of 2 holographic diffuser are available to do high-precision photometry with ALFOSC. The diffuser effectively scrambled the incoming light, providing a more constant and optimal (`top-head’) shape, with minimal light loss, significantly reducing any
systematic effects in the photometry. The diffusers provide a very stable stellar image with a size (~FWHM) of between ~5 and ~7.5 arcsec, depending on where they are mounted. See for more information: http://www.not.iac.es/instruments/alfosc/diffuser.html

– The SOFIN high-resolution Echelle spectrograph is again available. It only is offered to do circular spectro-polarimetry with the
medium-resolution (R~80,000) camera. SOFIN is not a common-user instrument: only limited support is provided.

Kind regards,
Thomas Augusteijn
Director, NOTSA

AOGS 2019 Abstract-Submission Deadline Extended to 19 February 2019

Dear All.

I’d like to let you know that the abstract-submission deadline for AOGS in Singapore this year has been extended to 19 February 2019. Submission and meeting details can be found here: http://www.asiaoceania.org/aogs2019/ and the abstract submission is done through the MARS Login at the top-right-hand side of the screen.

I would also like to draw your attention to two sessions: ST28 – Radio Heliophysics from Sun to Mud: How Radio Techniques can be Used to Study the Chain of Activity from Solar Origin to its Effects at Earth and Other Solar-System Bodies and ST 27 – General Session in Solar and Terrestrial Sciences. The full session details are below.

Many thanks,

Mario (Space Weather Secretary and ST President Candidate)

ST28: This session brings together all things Radio Heliophysics in nature, crossing all the sub-disciplines within Heliophysics from Solar, Heliosphere, Magnetosphere, Ionosphere, Planetary, Space Weather, and Beyond. The session encourages submissions around all aspects and use of radio in the Heliophysics domain, including but not limited to observations, data analyses, results discussions, modelling, use in space-weather forecasting, planetary science outside of the Earth’s own space environment, technique developments/needs, and future/developing instrumentation. Any and all abstracts linking into or using radio Heliophysics will be welcome in this session to try to bring the wider community into a single joined-up session.

ST27: This session is intended to cover all general contributions from the Sun to the Earth and beyond throughout the heliosphere. Contributions from helioseismology, solar physics, heliospheric science, space weather, magnetospheric physics, ionospheric physics, sun-planetary interactions, cosmic rays, and all aspects of the heliosphere and outer heliosphere are welcomed – particularly if they do not fit any of the more-specialised ST Sessions.

NAM Session: Active Region Laboratories

We would like to encourage abstract submission for the NAM 2019 session on Active Region Laboratories.

Active regions are of fundamental importance in Solar Physics as they are the primary source of a multitude of solar activity that occur on a variety of spatial and temporal scales. In particular, the formation and eruption of magnetic flux ropes, the generation and propagation of MHD waves, solar flares and the acceleration of energetic particles. In this session we bring together state-of-the-art models and high-resolution observations of active regions and their associated phenomena in order to review recent advances in the field and discuss requirements for future missions with an outlook towards active regions on other stars and stellar flares.

The abstract submission is now open.

NAM will take place at Lancaster University on 30th June – 4th July 2019

Software in Solar Physics Survey

The SunPy Project would like to conduct a survey about software use in solar physics. This survey is based on a similar one conducted by Ivelina Momcheva and Erik Tollerud in 2015, who surveyed 1142 astronomers about software use in astrophysics (https://arxiv.org/abs/1507.03989).

This short, 12-question survey will help us understand how to develop better tools and resources for the community. We would really appreciate it if you could take a few minutes to fill it out!

IAU Symposium 355

Registration, abstract submission and grant applications are now open

Dear Colleagues,

We are pleased to announce IAU Symposium 355 on “The Realm of the Low Surface Brightness Universe”, which will be held from July 8 to 12, 2019, at the Guajara Campus of the University of La Laguna in the island of Tenerife, Spain.

With this first announcement we open the registration, the abstract submission, and the possibility to apply for IAU grants, all through the conference webpage at http://www.iac.es/congreso/iaus355/

———————
Rationale and Key Topics:

IAU Symposium 355 aims to survey the denizens of the low surface brightness skies, at all wavelengths and resolutions, to show the richness of physical processes taking place in this regime, which has not been fully explored yet. From the Zodiacal light in the Solar System all the way to the cosmological backgrounds, and from the contributions of amateurs to space-based instrumentation, this Symposium will provide participants with a broad glimpse of one of the few last niches that remain to be explored.

A wide range of topics will be addressed:

– State-of-the-art in present and future ground- and space-based instrumentation for LSB observations
– Data analysis and management of upcoming LSB surveys
– The nature of interplanetary/cometary dust grains and meteoritic streams in the Zodiacal light
– Dust grains in the interstellar medium as traced by cirri
– Mass loss episodes, shocks and debris discs as traced by LSB features around stars; orphan SN and GRBs
– Low surface brightness features around galaxies: signatures of past and on-going accretion and their constraints on dark haloes
– The nature of ultra-diffuse galaxies and other galaxies discovered by LSB surveys
– The intracluster light and its role in galaxy evolution in clusters
– The circumgalactic medium of low- and high-redshift galaxies
– The cosmic web of large-scale filaments
– The UV/optical/IR cosmological background radiation and its fluctuations
– The role of amateurs in LSB observations and citizen science LSB projects

Influencing the future ESA archives (including for Solar Orbiter).

I’d like to briefly discuss an opportunity for you to influence the way you will be able to access data in the future from ESA. I am a member of the ESA Heliophysics Archives User Group (HAUS). This was all new to me as I personally hadn’t used ESA archives before but Solar Orbiter data will be available from them (http://soardev.esac.esa.int/soar-beta/#home).
The plasma community will know this better through Cluster, and there are planetary archives as well. SOHO is obviously there as well. https://www.cosmos.esa.int/web/esdc

The ESA HAUS committee want to collate short science cases on how to use their archives in different ways – this can be combining datasets such as planetary with solar, solar with astronomy, or modelling with anything. Is there anything would make your research easier? Enable you to answer science questions that are currently difficult now? Or enable you to address Solar Orbiter questions with more ease? jHelioviewer comes under the ESA wing for example. These science cases will be used to help mould how the archives will look in future. The science cases will be short, and your input is important for the future. Guidance for your input is given below – no more than 1 A4 page. Please send to me at l.harra @ ucl.ac.uk by the end of March.

Science case format:

Science goal: provide science questions that are currently challenging to carry out with separate archives.

Archives and modelling required: describe which datasets and archives are necessary to carry out this work.

Ideal situation of data sources: in an ideal world, describe how the data access and modelling interaction could be easier.… continue to the full article
