Lovely aurora. One of the best I have seen.
Here is October 16th forecast by Belgium's Royal Observatory at http://www.sidc.be/products/meu/
COMMENT: There is one active regions visible on the solar disk (NOAA 2725),
with alpha magnetic field configuration and one sunspot. No C-class flares
in past 24 h. Solar activity is expected to remain at low levels.No Earth directed Coronal Mass Ejections (CMEs) have been detected. Solar
protons have remained at background levels over the past 24 hours.The solar wind speed is at 520 km/s with interplanetary magnetic fields of
4 nT. The Earth is under the influence of a high speed solar wind stream.
Geomagnetic conditions have been quiet to unsettled, with an active period
at Dourbes (K = 4) on October 15 at 21:00 UT. More quiet to unsettled
conditions expected for the next 48 h (active periods remain possible).TODAY'S ESTIMATED ISN : 000, BASED ON 22 STATIONS.
Although tiny active region AR2725 is decaying, it seems to persist.
October 16 was spotless, but the 17th could show one or more sunspots at AR2725.
GOES X-ray flux shows solar activity in the A0 range, which is typical of solar minimums.
