“The Solar X-ray Limb III”, by Marina Battaglia and Gordon Hurford. RHESSI succeeds with an entirely new way to measure the solar diameter.
See sprg.ssl.berkeley.edu/~tohban/wiki/index.php/RHESSI_Science_Nuggets listing the current series, 2008 – present, and sprg.ssl.berkeley.edu/~tohban/nuggets/ for the original series, 2005 – 2008.
We publish these at roughly two-week intervals and welcome contributions, which should be related, at least loosely, to RHESSI science.
The IAU first PhD Prize Winners were just published online by IAU General Secretary Prof. Piero Benvenuti (www.iau.org/news/announcements/detail/ann17024/) and the 2016 IAU PhD Prize Winner of IAU Division E: Sun & Heliosphere is Dr. Shinsuke Takasao from Kyoto University, Japan. Congratulations!
Last year the IAU announced the creation of a new award, the IAU PhD Prize, to recognise outstanding scientific achievement in astronomy by PhD students around the world. In fact it is a series of awards, as each of the IAU’s nine Divisions selects a winner in its own field of astronomy.
At the 99th Meeting of the IAU Executive Committee the first winners of the IAU PhD Prize, for the 2016 year, were selected. They are:
Division A: none (no valid candidates)
Division B: Adrian Sven Hamers, Leiden University, the Netherlands, Hierarchical systems
Division C: none (no candidates)
Division D: Eric Robert Coughlin, University of California, Berkeley, CA, USA, The Evolutionary Pathways of Tidal Disruption Events: from Stars to Debris Streams, Accretion Disks, and Relativistic Jets
Division E: Shinsuke Takasao, Kyoto University, Japan, Fundamental Magnetohydrodynamic Processes of Solar Flares: Formation of Flare-productive Regions and Evolution of Flare Loops
Division F (ex-aequo): Laura Kreidberg, University of Chicago, IL, USA, Glimpses of Faraway Places: Intensive Atmosphere Characterization of Extrasolar Planets; and Caroline Morley, University of California, CA, USA, Exo-Planetary atmospheres Clouds and Hazes in Exoplanet and Brown Dwarf Atmospheres
Division G: Morgan MacLeod, University of California, Santa Cruz, CA, USA, Social Stars: Modeling the Interactive Lives of Stars in Dense Clusters and Binary Systems in the Era of Time Domain Astronomy
Division H: Long Wang, Peking University, Beijing, China, The dynamical evolution of globular clusters
Division J: Fabio Pacucci, Scuola Normale di Pisa, Italy, The First Black Holes in the Cosmic Dark Ages
Additional Prize for candidates from developing countries:
Division H: Yang Huang, Peking University, Beijing China, Stellar parameter determinations, and chemical and kinematical properties of the Milky Way based on the LAMOST Spectroscopic Survey of the Galactic Anti-Center
35 candidates submitted their PhD theses by the 15 December deadline and most of them were judged excellent by the evaluation panel of the relevant Division, making the selection particularly hard. In one case (Division F), there was a clear tie and the two winners will share the prize.
Each recipient receives airfare, registration fee and accommodation to attend the next IAU General Assembly, to be held between 20 and 31 August 2018 in Vienna, Austria, where their certificates will be awarded. The winners will also have the opportunity to present their research work in one of the sessions of the General Assembly.
The IAU congratulates all these winners, wishes them every success in their future careers, and looks forward to another crop of high-quality applications for next year’s award. The 2017 round is open for submissions until 15 December; the next set of winners will be announced in spring 2018 so they will also have the opportunity to attend the General Assembly in Vienna.

Solar variations have significant influence on the Earth’s space environment and climate via its magnetic field, irradiance and energetic particles. Long-term and reliable historical datasets of solar and stellar activity indices are crucial for understanding the variations and predicting the future solar cycle. Cosmogenic and radionuclides can extend our knowledge of solar variations back to the Holocene. There are a number of important and hot issues relevant to the evolution of solar activity and variability. These include, how to build up long-term consistent datasets, e.g., sunspot number and solar irradiance, how to realistically reconstruct the physical parameters, like the interior convection spectrum and photospheric open flux, based on the longest records, how to understand the relations among different indices, how to model the solar cycles based on the observed data. Furthermore, the progress in the understanding of the stellar variability and activity cycles helps us to understand the solar cycle over a much wider sample of Sun-like parameters.
We invite contributions on the following topics:
Requests for IAU Financial Support can be submitted until September 30th 2017. IAU grants are meant to support qualified scientists to whom only limited means of support are available, e.g., colleagues from economically less privileged countries and young scientists.

The International Study of Earth-Affecting Solar Transients (ISEST) Workshop is aimed at bringing together scientists from different countries to interact and establish collaborative links that can effectively address the physical mechanisms regarding the origin, propagation, and Earth impact of coronal mass ejections (CMEs) and other transient events. The ISEST-2017 workshop is the latest one of a series of workshops organized by the ISEST project, which is one of the four projects of SCOSTEP’s VarSITI program (2014-2018). The ultimate goal of the ISEST project is to develop the capability to predict the arrival and geoeffectiveness and other space-weather consequences of solar transients. The ISEST project, involving a truly global network of scientists, consists of seven active working groups: (1) data, (2) theory, (3) simulation, (4) event campaign, (5) Bs challenge, (6) Solar Energetic Particles, and (7) MiniMax campaign. The project provides a standing website for hosting events catalogs, data and presentations and offers a forum for discussion available at solar.gmu.edu/heliophysics/index.php/
The registration deadline of the workshop is July 15, 2017. Since there is a limited number of seats available, anybody registering after the 50th person may require additional approval from SOC for the participation. The deadline for submitting an abstract is August 15, 2017. A limited amount of fund is available for supporting young scholars. Please send an email along with your CV and tentative abstract to Kyungsuk Cho (email@example.com) before June 30, 2017 for the financial support. Registration and other information of the workshop can be found at “kswrc.kasi.re.kr/Workshop/isest2017” Note that the ISEST-2017 workshop shares the same time and venue with the 3rd COSPAR Symposium on Small Satellties for Space Research, but runs as an indepedent program.

Prediction of solar magnetic activity on various temporal scales is a fundamental element of space weather, which requires a wide range of theoretical and observational expertise in solar phenomena from the deep interior to the corona. Historical observations have revealed many features of cyclic variations of the solar activity; but these data are dramatically insufficient to draw a physical picture of global magnetic field evolution. New observational data, currently available from space missions and ground-based observatories, provide us with detailed information about solar dynamics and magnetism. However, because of the relatively short duration of data series and the great variety of data types and quality, it is challenging to assimilate these data in theoretical models and make reliable forecasts. The recent unexpectedly weak solar activity cycles, as well as observations of rotational and magnetic topology transitions in solar-type stars, suggest that the Sun and its magnetic dynamo are currently in a very interesting evolutionary stage. This could relate to the difficulty in getting a model of the Sun to produce solar-like – rather than anti-solar-like – differential rotation, to reproduce the rotation profile obtained from helioseismology, and to predict solar activity cycles.
The proposed session will combine the expertise of observers, theoreticians and modelers and provide a unique platform to discuss the current status and challenges for understanding solar and stellar dynamics and activity on different temporal and spatial scales.
During the session the following questions will be discussed:
1) What are the important links between the solar dynamics and activity from the interior to the surface and corona?
2) What additional observations would test the hypothesis that Sun-like stars undergo a transition from large-scale to small-scale magnetic field topology?
3) What additional observations and models are needed to reconstruct solar evolution to explain current dynamical properties?
Invited speakers: Travis Metcalfe (NCAR), Lisa Upton (HAO)
Organizers: Irina Kitiashvili (NASA Ames & BAERI), Mausumi Dikpati (HAO, NCAR), Todd Hoeksema (Stanford University), Michael J. Thompson (HAO & NCAR), Ricky Egeland (HAO & Montana State University)
