The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

This, the 30th edition of the "United States Government Printing Office Style Manual," is the first revision to this authoritative style manual since 2002. The "GPO Style Manual, as it is popularly known, is issued under the authority of section 1105 of Title 44 U.S.C., which requires the Public Printer, as head of the GPO to "dtermine the form and style in which the printing...ordered by a department is executed...having proper reagrd to economy, workmanship, and the purposes for which the work is needed." The Manual is prepared by the GPO Style Board, composed of proofreading, printing, and Government documents specialists from within GPO, where all congressional publications, and many other key Federal Government documents are prepared. The first "GPO Style Manual" appeared in 1894. It was developed orginally as a printer's stylebook to standardize word and type treatment and remains so today. Through successived editions, however, the "GPO Style Manual" has come to be widely recognized by writers and editors both within and outside the Federal Government as one of the most useful resources in the editorial arsenal. This new, revised version of the "GPO Style Manual" has been thoroughly redesigned to make it more modern and easier to read, and the content has been updated generally throughout in keeping with current usage.
