The MLSO instrument provide observations needed to understand the sun's continuos release of plasma and energy into interplanetary space. MK3 mk3 MK3-K Coronameter MK3 White Light pB Data (Polar Coords) MK3 White Light pB Data (Polar Coords) MK3_CPB These images are in polar coordinates and are ideal for azimuthal and radial scans. Polarization Brightness data are required for measuring coronal densities and computing masses. CHIP This is the ACOS CHIP Helium I 1083 nm intensity data taken every three minutes at MLSO. Provides a good indication of large scale structure of upper chromosphere and corona including active regions, prominences and filaments, coronal holes, filament channels, etc. CHIP_INT CHIP He 1083 nm Intensity CHIP He 1083 nm Intensity CHIP He 1083 nm Velocity This is ACOS CHIP Helium 1083 nm Velocity Data. Together with CHIP Intensity Data, this dataset provides a good view of activity in the upper chromosphere region, particularly prominence and filament activity and eruptions. This data is taken every three minutes. CHIP He 1083 nm Velocity CHIP_VEL Helium-I (1083 nm) images, collected with the Chromospheric Helium-I Imaging Photometer since April, 1996. Chromospheric Helium Imaging Photometer chp PICS H-Alpha Disk (Dark corrected) PICS H-Alpha disk data provides a good view into prominence and filament activity and eruptions, as well as flare activity. These images are taken every three minutes and have had minimal processing done. Only a dark subtraction and hot pixel cleanup has been done on these images. These images have not been rotated for p-angle. PICS_ASC PICS H-Alpha Disk (Dark corrected) PICS H-Alpha limb data provide views of solar limb activity by occulting the solar disk. These data are taken every three minutes. No processing is done on these data. These images have not been rotated for p-angle. PICS_LIMB PICS H-Alpha Limb PICS H-Alpha Limb H-alpha disk and limb images. The original Prominence Monitor (PM) was installed in February, 1980. In February, 1994, it was upgraded to become the Digital Prominence Monitor (DPM) by replacing a 35mm film camera with a high resolution (1534x1030 pixel) CCD camera. The Polarimeter for Inner Coronal Studies (PICS) instrument replaced the DPM instrument in September, 1997. PICS dpm H-alpha prominence and solar disk monitor PICS H-Alpha Disk PICS_DISK PICS H-Alpha Disk PICS H-Alpha disk data provides a good view into prominence and filament activity and eruptions, as well as flare activity. These images are taken every three minutes and have had a limb darkening correction applied as well as some contrast enhancement. Mauna Loa Solar Observatory data archive MLSO MK3_RPB MK3 White Light pB Data (Rectangular Coords) These images are identical to the MKIV pB data in polar coordinates, except for the coordinate system. Polarization Brightness data are required for measuring coronal densities and computing masses. These images are in rectangular coordinates. MK3 White Light pB Data (Rectangular Coords) K-Corona images in white light polarization brightness (pB). Mark-III (Feb 1980 - Sep 1999) has now been replaced by the Mark-IV Qualitative white light coronal images. These images have had an artificial vignetting function applied which reduces the radial density gradient in order to enhance contrast. These images are in no quantitative units. They are useful for viewing activity and making position measurements. The jpegs are made from these images. MK3 White Light Vignetted Data (Rectangular Coords) MK3_RPB_VIG MK3 White Light Vignetted Data (Rectangular Coords) MK4_RPB_VIG Qualitative white light coronal images. These images have had an artificial vignetting function applied which reduces the radial density gradient in order to enhance contrast. These images are in no quantitative units. They are useful for viewing activity and making position measurements. The jpegs are made from these images. MKIV White Light Vignetted Data (Rectangular Coords) MKIV White Light Vignetted Data (Rectangular Coords) MKIV White Light pB Data (Polar Coords) MKIV White Light pB Data (Polar Coords) These images are in polar coordinates and are ideal for azimuthal and radial scans. Polarization Brightness data are required for measuring coronal densities and computing masses. MK4_CPB MK4_RPB MKIV White Light pB Data (Rectangular Coords) These images are identical to the MKIV pB data in polar coordinates, except for the coordinate system. Polarization Brightness data are required for measuring coronal densities and computing masses. These images are in rectangular coordinates. MKIV White Light pB Data (Rectangular Coords) MK4-K Coronameter mk4 K-Corona images in white light polarization brightness (pB) (Sep 2000- present) of the solar corona from 1.12 to 2.79 solar radii.
