Digital realtime data

• Last hour
• http://www2.irf.se/maggraphs/rt1hour.txt gives you data for the last hour with times in hours and the three components (XYZ) in nT as preliminary deflections from the expected monthly mean.
• http://www2.irf.se/maggraphs/rt_iaga_last_hour.txt gives data in iaga format for the last hour in 1 minute resolution. Absolute values are presented based on absolute measurements made until 2024-07-23 07:04:11.
• http://www2.irf.se/maggraphs/rt_iaga_last_hour_1sec.txt gives data in iaga format for the last hour in 1 second resolution. Absolute values are presented based on absolute measurements made until 2024-07-23 07:04:11.
• Last day
• http://www2.irf.se/maggraphs/rt.txt gives ascii data for the last day in the format "yyyymmddhhmmss X Y Z" in nT as preliminary deflections from the expected monthly mean.
