<div>Dear all,<br>
<br>
</div>
Prof. Shadia R. Habbal (nominated by Hui Tian) from Institute
for Astronomy, University of Hawaii, will be our next <br>
Thompson Lecturer, and will come to NCAR from November 15th to
November 17th, 2011. Prof. S. R. Habbal, the current Chair <br>
of Solar Physics Division of the American Astronomical Society,
current Faculty Chair of Institute for Astronomy at the<br>
University of Hawaii, and the former Chaired Professor in
Solar-Terrestrial Physics at the University of Wales, is a <br>
leading scientist in solar and space physics. She worked also as
one year ASP term at NCAR (1977-1978). <br>
<br>
Prof. Habbal has over 100 publications in major refereed
journals, she has explored scientific problems in a very <br>
broad range of topics, notably coronal heating and solar wind
origin. Prof. Habbal was one of the three editors of JGR-space<br>
physics (2002-2006), editor of several books, and member of more
than 10 scientific committees (e.g. Solar Probe Advisory <br>
Panel, NASA Space Physics Subcommittee). She has received many
awards such as the prestigious Arab Thought Foundation Pioneer<br>
award (2004), NASA group achievement award (2000), Adventurous
Women Lecture Series Award (1998). <br>
<br>
<br>
Prof. Habbal is very easy to talk to and she is always willing
to give advice to young scientists. She speaks English, <br>
French, and Arabic fluently, with some elementary knowledge of
German. More information can be found at<br>

We will have FOUR major events: 1) two seminars, 2) two roundtable
discussions, 3) Potluck dinner and 4) individual meeting. The
detail information are listed as follow. <br>
<br>
<br>
FIRST, SEMINAR <br>
<br>
1) general audience seminar: Nov. 15th, <font color="#000000">11:00
- 12:30 PM</font> (<font color="#000000">11:00 - 12:00:

at ML Main Seminar Room.<big><br>
<br>
Abstract 1 for general audience</big>: Scientific
Discoveries from a Fleetingly Disappearing Sun<br>
<br>
The discovery of the solar corona would not have been possible
without the advent of total solar eclipses, which occur at most
once every year, and last at most a <br>
few minutes. Conceivably, the history of astronomical discoveries
and space exploration would have followed a different path in the
absence of total solar eclipses. It <br>
wasn't until the beginning of the 19th century that the corona was
established as an extension of the solar atmosphere beyond the
visible photosphere. The advent of <br>
imaging and spectroscopy around that time period marked the dawn
of scientific explorations of the solar corona, and led to the
discovery, almost a century later, that <br>
the dominant coronal emission was characteristic of hot gases at
temperatures exceeding a million degrees. With the invention of
the coronagraph by B. Lyot in 1930, <br>
and the dawn of space exploration in the early 1960's, total solar
eclipses were no longer the sole opportunities available for
remote sensing of the corona through imaging <br>
and spectroscopy. Nevertheless, eclipse observations continued to
offer unique opportunities for scientific discoveries. This talk
will focus on the scientific breakthroughs <br>
made with total solar eclipse observations, and on the discoveries
from recent eclipse observations, enabled by <big>advanced
digital recording technologies and image <br>
processing capabilities. <br>

Images of the corona taken during total solar eclipses are
snapshots of the state of the corona within the few minutes of
totality. Such observations capitalize on the <br>
diagnostic properties of the visible and near infrared wavelength
range, in particular, emission from broadband white light and
coronal forbidden lines, which include a <br>
number of ionized states of Fe, and other elements such as Ni and
Ca, to name a few. These images offer unique perspectives into the
quiescent and dynamic large scale <br>
structures of the corona and their thermodynamic properties,
starting from the solar surface out to a few solar radii. Despite
the abundance, at present, of uninterrupted <br>
space-based broadband white light and extreme ultraviolet
observations, with high spatial and temporal cadence, much can
still be learned from the short duration of <br>
eclipse observations that is not possible from space. An overview
of the novel results that have emerged from recent eclipse
observations will be presented, with particular <br>
emphasis on the role of prominences in the quiescent and dynamic
state of coronal structures.<big><big><big><big><big><big><big><span

To facilitate planning, please let Alex (<a
href="http://mailman.ucar.edu/mailman/listinfo/grad-postdoc-assn">ajahn
at ucar.edu</a>) know if you'll come and if you'll bring someone
(families welcome!)<br>
before Nov. 8st. And to make sure we have a good variety of food
to eat, please list what dish you'd like to bring on the wiki,

<br>
FOURTH, INDIVIDUAL MEETING <br>
<br>
The rest of Prof. Habbal visit will be devoted to individual
meetings with postdocs at NCAR. These meetings (30 minutes long) <br>
are a great opportunity to meet renowned scientists. And even if
Prof. Habbal is in a very different field than you, don't be <br>
afraid to sign up, because the speakers we invite normally have a
breadth of interests and can also offer you interesting insights<br>
on career development. So rush to sign up for a meeting, we only
have 16 spots. You can sign up here:<br>
