REPORT 01 REORGANIZATION

In his 13th Brown Bag Forum meeting with the staff, Firor addressed severalquestions he said had been asked in the previous two weeks.

THE RETIREMENT PLAN will go unchanged. Although our TIAA-CREF plan is"somewhat more generous than those at some universities," the Board decidedthat this was in keeping with the tenor of modern personnel policies, com-mended NCAR for our plan, and voted to leave it unchanged.

OUR NEW STRUCTURE with three main scientific divisions was approved, aswere the appointments that have been announced to date. These include:

I. Atmospheric Analysis and Prediction -- Cecil Leith

Akira Douglas i Philip

Kasahara Lilly Thompson Future

GARP Small Scale Climate ProjectsPrediction

II. Atmospheric Quality and Modification -- (vacant)

William Eric Allen John GilleSwinbank Urban and Future

THE SPACE SURVEY now underway is in the question-asking period, Firor said.In an effort to save funds, NCAR is examining the possibility of renting lessspace in town and putting more staff in the Mesa Laboratory.

THE SPECIAL MEMBERS MEETING, called for at the December meeting,is nowslated for Friday and Saturday, May 11 and 12.

THE SEARCH COMMITTEE FOR THE VICE PRESIDENT OF UCAR, reported back that theybelieve UCAR's structure must be more clearly defined before a search for a vicepresident can be undertaken. The committee does not plan further meetings.

INFORMATION FLOW will be somewhat more difficult at this time because com-plete changeovers in management and budgetary authority will be in process untilJuly 1. Everyone is urged to be alert to this factor and endeavor to keep bothold and new structures carefully informed.

The next brown bag forum will be held Monday, May 7, at 12:30 p.m. in theMesa Laboratory lobby.

AAAS DIRECTOR TO VISIT NCARNCAR has invited Janet W. Brown, director of the Office of Opportunities in

Science of the American Association for the Advancement of Science (AAAS) to beat NCAR on Friday, May 18. Dr. Brown will have a full day, beginning with apublic seminar in the morning. Thereafter, she will meet with NCAR supervisorypersonnel. Later in the day, she will hold informal discussions with anyinterested staff members after a general meeting with NCAR's women staffers.There will be a community reception for Dr. Brown that evening.

Sonia Gitlin, C4NW organizer of Dr. Brown's visit, says: "Janet Brown'svisit will give all scientific personnel in Boulder the opportunity to meet,discuss, and understand the expanding AAAS effort in minority opportunity."

Dr. Brown's office was created in June by the Association's Board of Directors.It was the result of the work of two committees: The Committee on Minorities inScience and the Ad Hoc Committee on Women, which had been assigned the task ofadvising the Board on how the Association should become involved in advancing thecause of women and minorities in science.

Dr. Brown is a former professor of political science at Federal City Collegein Washington, D. C.

The committee's first task, she said, is "to define its job and to identifyits priorities." In doing this, they will consider proposals made by the Committeeon Minorities and the Ad Hoc Committee on Women.


Among these proposals is the creation of a roster of women and minorityscientists; a national conference on that subject; and a follow-up to a surveydone last spring, of AAAS's affiliated organizations, to determine what theyare doing to create opportunities for women and minorities.

Un-C I"IISTS TO VIEW SOLAR COROJA ATUPREC-E.TED DISTANCES

Eight staff members comprise one of the many U.S. scientific groups going toAfrica for the June 30th solar eclipse. This eclipse will be the longest suchopportunity for observing the Sun's atmosphere that will occur in this century.

One HAO experiment is designed to complement the highly successful innercoronal telescope measurements with a new technique for viewing the Sun's outeratmosphere in infrared light at great distances--some 20 times the radius of theSun--out into space.

Since the Sun's outer atmosphere, or corona, is so faint it is usually oblit-erated by scattered sunlight, it can only be studied, observed or photographedwhen the Sun's bright disc is blocked out. This occurs at a total solar eclipsewhen the Moon temporarily occults the Sun. Since the Moon is beyond the Earth'slight-scattering atmosphere, the occultation is total. Thus, eclipse events pro-vide significantly better viewing than artificial occultation attempts by in-struments which must operate from the Earth's surface or aboard high-altitude

aircraft or balloons. These still have the light-scattering atmosphere directlybetween them and the Sun and, hence, are not totally occult~d,

One of these coronal cameras, designed by Gordon Newkirk, Director of HAO,records inner coronal brightness and polarization in the red portion of the visible

spectrum from the solar limb out to a distance of some four-and-one-half times

the radius of the Sun with a resolution of five seconds of arc--roughly analogousto distinguishing the diameter of a half-dollar at a distance of one mile. Thisexperiment will be operated by Joseph Rush, Lee Lacey, and Howard Hull, all ofthe HAO staff, and John Firor, Director of NCAR.

The secod HAO experiment, a coronal camera designed by Carl Lilliequist,records the outer coronal brightness and polarization in the near infrared be-

yond the visible spectrum in the distance range of two-and-one-half to 20 solarradii. This camera has a resolution of about one-half-minute of arc--less re-

solution than the other camera because of the lower resolution of infrared films.

This experiment will be operated by Lilliequist with technical assistance from

Lacey and Hull. Both the inner and outer coronal telescopes will be mounted ona common observing pad at the Loiyengalani, Kenyasite. Both experiments aremounted on unique wind-resistant, dual tripod assemblies designed by Lee Lacey.

A unique asset of the Newkirk inner coronal telescope design is a radially

graded filter which provides a varied density that precisely matches the drastic

change in brightness from the limb of the Sun at one to four-and-one-half solarradii where the Sun's brightness is 10,000 times less. Thus, the filter allowsone photograph to record a consistent view of the Sun's outer atmosphere or corona.This device was first used in 1966 in Bolivia.

The outer coronal telescope accomplishes its unique view of a 20 solardiameter field by a combination of a specially designed external occulting disc,

which casts a shadow to perform a similar light diminishing function to Newkirk'sradially graded filter, with film and filters sensitive only to the near infrared

portion of the spectrum. Reduced atmospheric scattering in this part of thespectrum reduces the relative sky brightness so that it is possible to distinguishthe faint outer portions of the coronal streamers.

* NCAR Staff Notes/No. 357Sheet 5

The near infrared experiment was first tried in Mexico in 1970 as an un-sponsored effort of Lilliequist and Edward Schmahl of the University of Colorado.The two scientists trekked to the Mexican site on a 3500-foot-high mountain westof Cameron. They used two 35 millimeter camera bodies, two adapted lenses, anda common amateur equatorial mount that viewed the eclipsed Sun and the Coronaaround it with the help of an external occulting disc between the lenses and theSun. The shadow cast by the external occulting disc in one camera system obscuredthe corona out to about five solar radii--near the outer radial extent of theNewkirk inner coronal camera. The other camera system with a smaller occultingdisc was designed to give considerable overlap with the inner coronal camera.

Both coronal cameras will record the brightness of their respective views ofthe corona and use three polarized filters to document the coronal polarizationin three directions 60 degrees apart. These photo series will help scientistsdetermine the intensity of the coronal and the direction of polarization at eachpoint by yielding information about the three-dimensional distribution of electrondensities in the corona. Combined with calculations of the coronal magnetic fieldfrom magnetograph observations of the Sun's photosphere, this information shouldhelp solar physicists form a coherent picture of how magnetic fields influencelarge-scale coronal structure. Such information is particularly useful inbuilding mathematical models to describe the electron density of the corona.

The four minutes and fifty-seven seconds of usable eclipse time is soshort that all sequencing of polaroids and clear photos in several differentexposure sets will be automatically accomplished by a programmer system operatingservomotors. These observations will be made from one of the main NSF sites atLoiyengalani, Kenya. Another group of three HAO staff members--Oran White, TomBaur, and Gary Emerson--will be journeying some 70 miles north to an isolatedspot on the northeastern shore of Kenya's Lake Rudolf to be near the edge of thesolar shadow. From here, they will attempt to observe solar spicules, the tinygas spikes that protrude above the major chromospheric layer of the Sun.

The NCAR/HAO scientists will be joining the national U.S. expedition beingfinanced by NSF. NSF appointed FOF to serve as U.S. expedition organizer. Thisincluded arranging for transportation of all participating scientists and their40-odd-tons of equipment. Support in the field in Africa covers the entire rangeof necessities from food, water, and housing to medical and logistics support of

90 U.S. scientists planning experiments and observations at the 1973 eclipse.William Curtis is handling this NCAR effort for NSF and Gene Prantner is thefield manager for the Loiyengalani site.

FREDJ FIDEL PREPROCESSORS

ARE NEW SUBJECT COURSEThe Computing Facility has initiated a series of mini-courses to provide the

opportunity for programmers to continue learning and developing new ideas aboutprogramming.

The first course was an introduction to data structures taught last month byLee Osterweil from the University of Colorado. As there was an enthusiastic re-sponse to this course, we are planning another mini-course.

The topic is preprocessors (such as FRED and FIDEL). Rich Helgason willconduct the daily class from 10:30 to 11:30 a.m. in the Fleischmann Buildingfrom May 7 through May 11.

Since the course meets every day for a week, the treatment will be fairlyintensive0 He welcomes any member of the NCAR staff, however, since attendance

* at all five lectures is required for programmers who sign up, any non-programmerswho want to attend are encouraged to follow the same rules as for programmers.If you are interested, please contact Sabrina Roper, NL room 8, ext. 566.
