I am a new user and dont know anything about JSOC?
Data are stored in the JSOC in "Data Series" and you need to use the correct format to access it.
All HMI data have the prefix "hmi.". Similarly, all AAI data have the prefix "aia"; MDI data have the prefix "mdi", SHA data have the prefix "sha."and IRIS data have the prefix "iris".The typical data format is the series name followed by the data and time. For example:
hmi.M_45s[2011.01.01_01:30:00_TAI/30m] refers to the LOS Magnetograms on the date 2011/01/01 at time 01:01:30_TAI for an interval of the next 30 min. Similarly, hmi.Ic_45s[2011.01.01_01:30_TAI-2011.01.01_02:00_TAI]. This query requests all HMI continuum data for January 1, 2011 between 01:30 and 02:00 TAI.
