As of Fall 2015, SLCC charges $100 for the basic TEAS (V) exam. These fees are subject to change. There have been price increases in the past and when you schedule a time to take the exam the Health Sciences Test Scheduler will have the current costs.
Learmonth Observatory. Learmonth Solar Observatory is jointly operated by Bureau of Meteorology - Space Weather Services and the US Air Force. The observatory is the site of one of six solar velocity imagers in the world-wide GONG (Global Oscillation Network Group) network operated by NSO (US National Solar Observatory). Observing instrumentation includes:
N2LVI's Quick Guide to HF Propagation Using Solar Indices. SOLAR FLUX INDEX (SFI) While increasing SFI may be good for HF propagation, it also tends to correspond with high Ap and K indices, which cause D-Layer absorption and noisy band condition. Solar flux is measured in solar flux units (SFUs). It is the amount of radio noise or flux emitted at a frequency of 2800 MHz (10.7 cm, hence is it also called the 10.7 cm flux index). NOAA broadcasts geophysical alert messages over WWV at 18 minutes after the hour and from WWVH at 45 minutes after the hour.
