Mees Solar Observatory (MSO) is located on Haleakala, Maui, at 165E longitude and 20N latitude. MSO instrument operation hours vary from 1800-0300 UT in December to 1630-0400 UT in June. A searchable catalog called SPAM (Spectroscopy and Polarimetry at Mees) contains MSO data logs (not data). Some MSO data are available on line. Other MSO data can be obtained through the Data Use Coordinator, canfield@mamane.ifa.hawaii.edu.
SPAM logs (and searchable attributes, in addition to date, day of year, and time) include: MSO Log (instrument, NOAA AR, data type, observing setup), SEL Event List (NOAA AR, X-ray Class), SEL Region Report (NOAA AR), Yohkoh Orbit Summary, Yohkoh SXT Quiet Mode PFI Observations (latitude, longitude, X-ray and optical image size), Yohkoh Flare Observations (latitude, longitude, specific channel counts or ratios). SPAM runs on a Sun Unix workstation at MSO, and is available over Internet. Simply access (e.g., telnet) koa.ifa.hawaii.edu (128.171.167.1) from any vt100, Sun, or xterm emulator. Log on as spam (lower case); there is no password. New users are asked to read release notes and hints.
Vector magnetograms from the MSO Stokes Polarimeter are available on line for about a month after acquisition. These data are available by anonymous ftp over Internet. Use ftp koa.ifa.hawaii.edu, log in as anonymous, provide your name as the password, and then respond to the ftp prompt with cd pub/stokes. Use get to obtain a copy of the README file for further information and conditions for data use.
