Scientific Amateur Astronomy
A forum where amateurs can discuss their contributions to fields such as spectroscopy, photometry, astrometry, interferometry, and radio astronomy. Astronomical objects of interest may include variable and carbon stars, pulsars, supernovae, AGNs, exoplanets, asteroids, and short-lived energetic phenomena such as GRBs. The presentation of quantitative observational measurements, techniques used for acquisition, and relevant ensuing discussion are especially welcome.
