The data presented on this website is far from a complete representation of all of the available MLSO data. For example, there is MK3 data available as far back as 1980. We also provide CHIP Helium 10830 data and PICS H-Alpha limb and disk data back to 1996. To get this data, simply email DATA REQUESTS (mlso_data_requests@ucar.edu) and we will gladly provide you with the data you need.
