2014 Award Selection Nominations were solicited June 4, 2014 Participating award committee members were –Dave Herald, NSW, Australia (recipient 2007 award) –Edwin Goffin, Belgium (recipient 2008 award) –Steve Preston, USA (recipient 2009 award) –Hristo Pavlov, Australia (recipient 2010 award) –Kazuhisa Miyashita, Japan (recipient 2012 award) –Graham Blow, New Zealnd (recipeint 2013 award) –Colin Haig, Ontario, Canada –Terrence Redding, Florida, USA (chairman) Award committee goals: –select recipient of 2014 DaBoll and Laird awards

Eligibility (current) Who is eligible for an award? Anyone who has made significant contribution to occultation science or the work of the IOTA Excluding sitting IOTA officers & award committee IOTA membership not required Who can make Nominations? No defined restrictions at this time “Call for Nominations” made via Yahoo group effectively restricts nominators to active occultation community Encourage wide distribution of call

Deliberations Total of 18 nominations received. 5 individuals for the DaBoll and 3 individuals for the Laird. 2 were ineligible Some nominees were nominated more than once All were excellent candidates All communication conducted by –private to the committee –independent of IOTA officers, unless a committee member This year we again made a deliberate effort to encourage others to forward the request for nominations to other lists, mail groups and astronomy related organizations world-wide

Deliberations, cont. Effective nomination – written essay - documentation –Who, what, when, how Approach was “discussion to reach a consensus” (not “majority voting”), considering: –Documentation provided with nominations –Experience & personal knowledge of the candidate’s contributions. Members were asked to select their top picks to be considered and discussed. Then, narrow selection to one candidate The selectees were unanimous at the end of second round for both the DaBoll and Laird Awards

Brian Loader

Slide retained as a place holder

Brian joined the RASNZ Occultation Section in 1980 and immediately adopted a prominent role as a prolific observer of total and grazing occultations. In the same year He instituted the Jovian Satellite Eclipse programme which he then co-ordinated for more than 20 years. He promoted and co-ordinated observations of the mutual events of the Galilean satellites across multiple seasons. He initiated and continues to co-ordinate the double star programme for the determination of true separations and PAs from geographically separate occultation observations. Observers from around the globe contribute to this programme, which has resulted in a string of publications, including a number in the JDSO. Brian Loader

Brian continues to be one of the top observers of lunar occultations worldwide, as he has been for the observation of minor planet occultations within the Australasian region since predictions first became available. (2010) Brian reported on 46 events John Talbot noted, Brian has also been a regional co- ordinator and reducer for total occultations for many years, a role which has required him to interact with and provide advice to almost every new observer in this part of the world Together with his wife Pauline, Brian has for many years prepared and published annual summaries of upcoming bright total and grazing occultations for all of Australasia. These have materially assisted in attracting new observers to these events. Comments by Graham Blow Brian Loader, cont.

Gordon E. Taylor

Is the father of asteroidal occultations, predicting these events since the early 1950’s and thereby securing the first definite observation of such an event In the mid-1970’s, he spearheaded the effort to expand the predictions of additional asteroids as ephemerides improved, and better star catalogs became available. He was the first to use special astrometric observations to improve the predictions of events, a technique which proved to be crucial before the release of HIPPARCOS data in He worked closely with IOTA for many of the first asteroidal occultations we tried, such as the occultation of gamma Ceti A by (6) Hebe on 1977 March 5 that resulted in Paul Maley’s observation of a secondary occultation, largely responsible for starting IOTA’s claims that some asteroids likely have satellites. Besides occultations by minor planets, Gordon also predicted occultations by major planets, notably the occultation of Regulus by Venus on 1959 July 7, and the occultation of beta Scorpii by Jupiter (and Io) on 1971 May 14. Gordon also worked in the Her Majesty’s Nautical Almanac Office (HMNAO) at the Royal Greenwich Observatory, where he also was instrumental in the programming for lunar occultation predictions and reductions, as noted by Alex Pratt in his article about the occultation machines in the latest issue of JOA. He was the longest-serving Director of the Computing Section of the British Astronomical Society from 1974 to David Dunham Gordon E. Taylor
