The CAS
Space Weather Monitoring Program
Stanford
University's Solar Center has developed space weather monitors. These monitors detect changes to the Earth’s
ionosphere caused by solar flares and other disturbances. We built our own 4x4
foot square loop antenna. Data collection and analysis is handled by a local
PC. Stanford provides the centralized data repository. Here users can see and
compare data from sites around the world
What is a
Space Weather Monitor?
Our space weather monitor measures the effects on Earth of
solar flares by tracking changes in very low frequency (VLF) radio
transmissions as they bounce off Earth’s ionosphere. The VLF radio waves come
from a Naval Submarine Transmitter in Cutler Maine. Signal strength of these
VLF waves changes as the Sun affects Earth’s ionosphere, adds ionization, and
thus alters where the waves bounce. Our monitors track these changes in signal
strength.
What does SID Data Look Like?
To the left is our SID data graph for October 10,2023 to
compare to the GOES ( Geostationary Operational Environmental Satellite ) X RAY
Flux. The y-axis of the graph indicates signal strength, and the x-axis time,
in this case 24 hours. Note the change of the signal strength at sunrise and at
sunset. Also note the Moderate M class and two Low C class solar flares.
