Observation of Meteors for the Years 1935–1938 in New Zealand. Fourth Report Of The Meteor. Section Of Tee N.Z. Astronomical. Society, Inc. By R. A. Mcintosh, F.R.A.S. [Read before the Wellington Branch, July 26, 1939; received by the Editor, July 27, 1939; issued separately, March, 1940.] This report, covering the work performed in the four-year period 1935-38, is the fourth published by the Meteor Section of the New Zealand Astronomical Society, Inc., the earlier reports having been published in Transactions of the New Zealand Institute, vol. 60, p. 448, and vol. 63, p. 443, and Transactions of the Royal Society of New Zealand, vol. 66, p. 60. These reports have been reprinted and distributed as Bulletins nos. 5, 21 and 24 of the New Zealand Astronomical Society. The attention of members of the Meteor Section has been concentrated mainly on the ordinary routine of recording meteors in extended watches for the purpose of determining centres of radiation and rates of activity. The work has proceeded very slowly, because the personnel has always been small, but the experience gained by members over the years has resulted in a very satisfactory standard of accuracy being attained. As a result of this steady endeavour on the part of a few, the total meteors recorded by the section during the twelve years of its existence is 13,126, from which over one thousand radiants have been deduced. While this figure is no more than other meteor groups can produce in a single year, it must be remembered that the New Zealand work is being performed in the southern celestial hemisphere, where no other group or individual has observed for more than a short period. The data we are collecting are therefore of particular value in many ways. A stage has now been reached when the section must gain fresh observers if the valuable work is to continue. One of our most energetic members, Mr. M. Geddes, has now become Director of the new Carter Observatory, upon which his friends in the Meteor Section most heartily congratulate him. This appointment robs the section of a very active worker. Similarly, our work has now reached a sage where the writer must concentrate more upon the production of articles covering many phases of the work achieved, together with theoretical papers, and will probably in the next year or so be able to find time only for special researches as the need arises. It is to be hoped, therefore, that members of the Society who are not actively observing will step into the breach and help to continue the work

The following table summarises the work performed daring the period covered by the report:— Observer. Nights. Time. Meteors. h. m. Bateson (B) 1 2 35 18 Geddes (G) 39 74 4 1,162 Fairbrother (F) 34 73 44 874 McIntosh (M) 33 40 15 940 Total 107 190 38 2,994 Reports of telescopic meteors were received from members of the New Zealand Astronomical Society during the period as follows:—Bateson, 3; Bryce, 1; Geddes, 22; McIntosh, 14; Morshead, 5; Smith, 15; Sofield, 1. Total, 61. Details of fourteen bright fireballs have been collected from the public, most of which await investigation. (Unfortunately, although they contain several very interesting objects, publication cannot be achieved while more important meteoric topics are awaiting attention.) Large numbers of observations of isolated fireballs are also in hand, and my thanks are due to the Dominion Observatory, the Carter Observatory, and many individuals too numerous to mention, for making these reports available. The seven papers published during the period by the Director are indicative of the results achieved by the Meteor Section to date. The Ephemeris of the Eta Aquarid Radiant (Monthly Notices Royal Astron. Soc., 95, 7, 601; 1935, May), while tracing the day-to-day motion of this radiant, also demonstrated the accuracy which can be attained in visual meteor work, and is especially valuable at the present time while mathematicians are attempting to disparage the amateur meteor worker. The Index to Southern Meteor Showers (Monthly Notices Royal Astron. Soc., 95, 8, 709; 1935, June) is particularly valuable to members of our Section in that it provides the first indication of what minor radiants may be expected at any time. The Velocities of Meteor Streams (Monthly Notices Royal Astron. Soc., 96, 7, 704; 1936, May), The Telescopic Determination of Meteor Radiants (Journal Brit. Astron. Assoc., 46, 2, 73; 1935, Dec), and Meteor Static (Journal Brit. Astron. Assoc., 44, 3, 123; 1937, Jan.) open up new ground. In The Determination of the Real Paths of Fireballs (Journ. R.A.S. Canada, 32, 1, 1; 1938, Jan.) a complete method of dealing with large numbers of reports by inexperienced observers is published, I believe, for the first time in English. Finally, the first indication of the variation in the numbers of meteors throughout the year was given in a paper read at the Auckland sessions of the Australian and New Zealand Association for the Advancement of Science and later published in America (Popular Astronomy, 46, 9, 516; 1938, Nov.).

In the preparation of this report the existence of some radiants additional to those listed in the Index to Southern Meteor Radiants was disclosed. These are given in the following table:— New Radiants. No. Duration, Radiant. No. of Radiants.

The publication of such agreements does not necessarily indicate that the meteors are definitely debris of the comets particularly named. Comet Accordances. Object. Date. Radiant. Remarks. Comet Schaumasse Mar. 30 298.5°—9.64dE Davidson. Radiant 859 Apl. 3 294 —99 4/6 meteors. Comet 1877 ii Aug. 9 32.0 —18.5 Weiss. Comet 1852 ii Aug. 10 40-5 —13.5 Weiss. Radiant 1000 Aug. 2 39.0 —17.5 4 meteors. In the following table the details concerning the various observations are given in the manner usual to these reports. Apart from the date and time spent observing, from which the hourly rate is derived, a factor is estimated by each observer allowing for any hindrances to observing such as clouds or haze. With this factor the observed rate is corrected to a theoretical rate (column 8) for perfect observing conditions. The estimation of rates is not attempted in very short watches or where the factor is so small as to cast doubts upon the reliability of the corrected rate deduced.

Some interesting points can be gleaned from a perusal of this table, which can only be indicated here. Take, for example, the date, 1935, May 6. Observing about the same time, Fairbrother saw 14 meteors an hour in a clear sky, while McIntosh saw 26 an hour, also in clear sky. The difference between the rates can safely be ascribed to the inexperience of the former observer, who had just commenced working for the Section, and who apparently missed a number of the fainter meteors. The higher rates obtained by Geddes, on the other hand, when compared with those of McIntosh (both experienced observers) is an index to the difference between country and town observations.

In the column “Observer” the various observers are denoted as follows: Bateson (B), Fairbrother (F), Geddes (G), and McIntosh (M). The observing stations also are abbreviated: Auckland (A), Apia, Samoa (Ap), Canton Island, N.Z. Solar Eclipse Expedition's site (C), Chatham Island (CI), Ermedale, Southland (E), New Plymouth, Taranaki (NP), Otekura, Southland (O). South Hillend, Southland (SH), Tadmor, Nelson (T), Taradale, Hawke's Bay (Td), Wellington (W). The list of radiants which follows is in the same form as that used in the previous reports, being arranged in order of date (irrespective of year), at least four meteors observed on one night and intersecting within a circle 2 degrees in diameter, or five meteors on adjacent nights, or one stationary meteor, being required to form a radiant. Criticism has been levelled at the number of radiants in earlier reports based on very few meteors. The Director is reluctant to abandon these, in a practically virgin field such as we are working in. Some consolation can be derived from the fact that 75 per cent, of the present list find confirmation in other radiants observed in New Zealand or elsewhere, which is indicated by naming the radiant in the “Remarks” column. Actually a portion of any radiant list must be erroneous, and the same faith cannot be placed in a list such as the present one as can be given to the Index Catalogue previously mentioned.

In the “Remarks” column, D refers to Denning's General Catalogue of Meteor Radiants, the first figures to the group, the final ones to the radiant number; BAA to the radiants of the British Astronomical Association; numbers with the initials NZ prefixed refer to radiants in reports of the Meteor Section already published, while S.I.C. refers to centres of radiation published in the Southern Index Catalogue. In all cases where the radiants are named, other radiants have been found confirming those now published. The Director wishes to express his thanks to all the observer mentioned in this and preceding reports, by whose assistance the Meteor Section has accumulated an important mass of data, and look; forward to their continued co-operation in the future.
