Multicolor Active Galactic Nuclei Monitoring

Multicolor Active Galactic Nuclei Monitoring or MAGNUM was a project completed in 2008, that used a 2 meter (78.7 inch) telescope at Haleakala, Hawaii.[1] The project started in 1995, and with telescope observations starting in 2000 for the scientific study of active galactic nuclei.[2] It was run by the University of Tokyo, the National Astronomical Observatory of Japan, and Australian National University.[1][3] MAGNUM was one of the telescopes that observed a cosmic explosion billions of years away in 2005.[4] The telescope was used for a long-term study of the size of the universe;[5] for example it studied the Seyfert 1 galaxies NGC 5548, NGC 4051, NGC 3227, and NGC 7469[6] The telescope was located at the Haleakala Observatory and was installed in north dome previously used by LURE.[1]

This was an astronomy project that used an automated telescope to look for AGN at visible and near infrared wavelengths.[7]
