February is the secondmonth of the year in the Gregorian Calendar. It is the shortest Gregorian month and the only month with the length of 28 or 29 days. The month has 29 days in leap years, when the year number (eg 2004) is a multiple of four (but not of 400). In other years the month has 28 days.
February was named for the Roman godFebruus, the god of purification. January and February were the last two months to be added to the calendar, since the Romans originally considered winter a monthless period. This change was made by Numa Pompilius about 700 BCE in order to bring the calendar in line with a standard lunar year. Numa's Februarius contained 29 days (30 in a leap year). Augustus is alledged to have removed one day from February and added it to August, (renamed from Sextilis to honor himself), so that Julius Caesar's July would not contain more days. However there is little historical evidence to support this claim.
February was nominally the last month of the Roman calendar, as the year originally began in March. At certain intervals Roman priests inserted an intercalary month, Mercedonius, after February to realign the year with the seasons.
Historical names for February include the Anglo-Saxon terms Solmoneth (sun month) and Kale-monath (named for cabbage) as well as Charlemagne's designation Hornung.
Feb 18 evening and Feb 19 morning are quite variable compared to the quiet periods before and after.
During the 20-21 LT period on Feb 18, there is some hint of a drop in He+ concentration corresponding to the deep trough overhead Millstone, although this length pulse cannot easily resolve things in the low density region.
In particular, Feb 19 02 UT F12 and F14 passes show depletions in density extending down to 35 deg latitude, agreeing with MHO onset of large overhead density drop at 20-21 LT (01-02 UT).
FEBs are an efficient and effective force for progress.
Originally ten FEBs were created in major centers of Federal activity to serve as field level organizational structures comprised of the highest level official of each Federal agency.
In the FEB's primary area, which is the immediate L.A. area, the Board represents approximately 100,000 Federal employees and approximately 163 Regional, District, and Area Federal offices and commands.
