It contains formats and coding rules for solar flares, solar radio spectra, virtual height profiles, and total electron content and scintillation reports. Compliance with the publication is mandatory, and it includes limits on uncertainty, flux reporting, and burst reporting.
Applies to: This publication applies to all personnel responsible for weather operations to include AF Reserve, Air National Guard (ANG) and government contractors performing weather operations in support of Federal missions.
Fixed file times will use DDHHmm format. (paragraph 2)
Use this code to make event-level or routine reports of solar flares as observed with an optical telescope viewing at a wavelength of 6563Å (Hydrogen- alpha). (paragraph 3)
Do not report mean flux for noise storms or fluctuations; instead encode "000". (paragraph 2)
Do not report bursts of less than 100 sfu unless they are significant and/or contribute to the understanding of what is occurring. (paragraph 9)
Virtual height is the apparent height of a reflecting layer.
