Page 39 - Serpentis. Each region extends 5' north and 5' south of the declination of the corresponding bright star. It is desirable that these charts should be made as complete as possible, and it is hoped that astronomers having the use of powerful telescopes will assist in accomplishing this object. They will confer a favour upon the Observatory of Harvard College by comparing these charts with the regions which they represent, and marking upon them the places of any additional stars which may be visible.

Page 270 - O."09, which closely agrees with the value 42° 22' 47. "63 found last year by the small almucantar. The character of the various results given above encourages the hope that the use of the almucantar may become a permanent part of the work done at this Observatory. Should the results prove no more accordant than those of other instruments, the fact that they are obtained by an entirely independent method would free them from many of the errors which are commonly repeated in meridian observations.

Page 273 - Pickering gives a list of about 150 variables which have been observed during the year, with the number of nights on which each star was observed by the astronomer whose designation is attached to the number. It is hoped that observers of variable stars will continue to furnish accounts of their work during each year as soon as possible after its close. It is desirable that these accounts should be received at the Harvard College Observatory as early as February 1 of the following year. * ' Proceedings...

All my investigations, whether through observations at the sea level or at an altitude of nearly 15,000 feet, lead me to believe it probable that the mean absorption of light (and of heat also) by our atmosphere is at least double that -which is customarily estimated, and also to conclude that fine dust particles, both near the surface...
Page 169 - Greenwich civil time, starting at midnight and reckoning from oh. to 24?)., which would correspond with, the universal time recommended by the Washington Conference. The change from astronomical to civil reckoning has also been made in all the internal work of the Observatory, and has been, carried out without any difficulty. Greenwich civil time is found to be more convenient on the whole for the purposes of this Observatory, but its introduction into the printed astronomical observations has been...
Page 170 - Campbell's sunshine instrument during 1886 was 1228, which is about twenty hours above the average of the preceding nine years. The aggregate number of hours during which the sun was above the horizon was 4454, so that the mean proportion of sunshine for the year was 0^276, constant sunshine being represented by I.
