Updating bar plots of yesterday and today

The bar plots show the hourly (in even hours) maxima changes in the horizontal magnetic field components in units 0.01 nT/s and updated with 10 min resolution. The magnetic field data have been recorded at the Nurmijärvi, Sodankylä and Kevo observatories during yesterday and today. The magnetically quiet hours are marked with blue bars and the disturbed hours with red bars. An hour is considered as disturbed if the value in scale of the plot exceeds 30 in Nurmijärvi or 50 in Sodankylä, Kevo and Kilpisjärvi.
