When we think astronomy we generally think of optical astronomy, but the electromagnetic spectrum covers a much larger set of frequencies than just optical, at longer wavelengths, past infrared, electromagnetic waves are referred to as 'radio' and these pages are dedicated to the study of the universe at these wavelengths.

Radio astronomy is new (March 2011) to CMHAS, so our experience is also limited, these pages will try to explain how to observe at radio wavelengths, the approach is to start with easy low cost projects and working our way up to more advanced studies.

Sudden Ionspheric Disturbances

Frequency: 20-25kHz (VLF)
Cost: zero to ~£200 depending on approach used
Area of Study: Solar activity
Difficulty: Easy
More Information: Sudden Ionospheric Disturbances

Meteor Observations

Frequency: 30-150MHz (VHF)
Cost: ~£200
Area of Study: Meteor shower profiling and peak detection, variation in sporadic meteors with time and date.
Difficulty: Easy - Medium
More Information: Radio Meteors
