Show ANNULAR ECLIPSE OF THE SUN On the IGth of March will occur an annular an-nular eclipse of the sun visible in the United States and British America It8 tile return of the annular eclipse 01 February 12 18n In 1831 the central line pahfced over Texas in a northeaterlj direction being last visible on this continent conti-nent in parts 01 Virginia and North Carolina Caro-lina At this return the path will be much further north The eclipse will be annular over a line from Cape Alendocino California in latitude 4U degrees to < jrreenlaud in latitude 71 degrees It is estimated that the eclipse will be annular over a path about seventy miles wide The only towns of consequence in the I United states within this belt are Eureka California and Bozeman Montana At St Paul the eclipse will obscure five sixths of the sun but will not be annular At Chicago seventenths of the sun will be hidden From New York the obscuration obscura-tion will be somewhat less but sufficient to render the eclipse a most interesting event The eclipse will be annular because the cone ot the moons shadow does not reach the earth It will appear annular at these places nearly in the line of the point ol the cone In an annular eclipse a rmg of sunlight surrounds the moons shadow the moon being at such a distance dis-tance tliat it does not cover the whole of the suns disc Until recent years annular an-nular eclipses have been neglected by astronomers but dining the last one borne very important observations were made by the ii reach astronomers and it is probable that some effort will be made to observe the coining eclipse At all events the partial phase which will be visible here will be carefully observed it the weather permits The time of its occurrence oc-currence is very tavorable for careful observation ob-servation In Rochester the eclipse will begin at about 11 oO in the morning local time and end at 2uO in the uteruoon It would be well for those posbescing telescopes tele-scopes in this city to confer together for the purpose of preparing for systematic observations Efforts will be made to plioiograph eclipse during its entire progress if the sun is not wholly obscured by clouds The event may turn sh an opportunity to determine whether the moon has anything like an atmosphere As the sun is likely to show a number of spots of considerable extent upon the date of the eclipse it will be observed with added interest Telescopies who have not shade glasses for solar observation observa-tion will find it very interesting to throw the suns image upon a white screen a little removed from the eyepiece of the telescope Rochester Democrat |
