Day-camp for children at the IAU GA
In collaboration with the educational programme Universe Awareness (www.unawe.org) and Sterrenlab (www.sterrenlab.com), the International Astronomical Union is organising a day-camp for children of astronomers attending the General Assembly in Beijing. This programme will allow parents to attend the conference in a family friendly environment combining professional duties and family needs; the day-camp will offer a rich programme of science and cultural activities.
You can find more information about the UNAWE Day Camp at: http://iau.org/scientific_meetings/iau_ga_2012/special_events/unawe_workshop/
The following possibilities are available for financial support:
SPD Studentship and Metcalf Travel Award programs
Thanks to the generous support of the SPD Studentship Committee (funded by NSF), and the SPD's Metcalf Travel Award program, we will be able to provide partial financial support for early career researchers.
SPD Studentship: available to students enrolled at a US University, who have not yet completed their PhDs. Metcalf Travel Award: avalaible to researchers who have completed their PhD no more than five years before the start date of the General Assembly (August 20, 2012) and are members of the Solar Physics Division of the AAS.
These awards will be assigned jointly with the organizers of the other solar-related events at the GA (IUAS 294 ; JD3 ; SpS10). If interested, please submit an abstract, and send a 1-page CV and a letter of recommendation to iau_sps6@arcetri.astro.it https://webmail.obspm.fr/src/compose.php iau_sps6 @ arcetri.astro.it before February 29, 2012, specifying also which solar events you are interested in attending.
IAU travel grants
The IAU is offering a limited number of grants to support participation at the XXVIII IAU General Assembly. Grants are usually available to young astronomers and researchers from less privileged countries. For more information, please consult the IAU website at http://www.iau.org/grants_prizes/iau_grants/ga_events.
