    3939The bar chart below presents essentially the same data. The six series downloaded during the first quarter of 2021 from the NSO remote site are hmi.s_720s, hmi.m_720s, hmi.v_45s, hmi.ic_45s, hmi.m_45s, and aia.lev1. For each series, the green bar represents the number of data download requests for that series that succeeded (the web server had status 200) while the red bar represents the total number of requests (whatever the status the web server had).

     43This again shows that most requests are for AIA data. It also shows that while for AIA data most downloads succeed, that is less likely the case for HMI. The plot below shows the number of failed dowloads (not status 200) on the X axis with the number of requests for HMI data on the Y axis for this time period. The two appear correlated. This suggests that the system is having problems when users request HMI data.
