Sun online. Solar activity. 1st of September 2013

The solar events of the last 24 hours:

  • Solar activity was eruptive featuring 1 C-class flare (C2.6) originating from AR NOAA 11836. Both AR NOAA 11835 and NOAA 11836 have a possibility in producing M-class flares.
  • A partial halo CME Coronal Mass) was detected by LASCO C2 on August 31st around 20:48 UT which could be assiociated with the C2.6 flare. This CME is mainly westward directed (possibly only a glancing blow) and due to the relative slow speed of 400 km/s will probably not have any influence on geomagnetic conditions.
  • Current solar wind speed is around 550 km/s.
  • Currently,  on the Sun there are 3 active regions with sunspots.

Geomagnetic conditions where quiet in the past 24 hours, but the CME of
August 30th 2:48 UT might still arrive and potentially result in minor
storm levels (K=5). The CME of of August 29th 06:00 UT is expected to
arrive with a shock on September 2d in the evening resulting in active
conditions (K=4).

Fire on Earth

Explanation: Sometimes, regions of planet Earth light up with fire. Since fire is the rapid acquisition of oxygen, and since oxygen is a key indicator of life, fire on any planet would be an indicator of life on that planet. Most of the Earth’s land has been scorched by fire at some time in the past. Although causing many a tragedy, for many places on Earth fire is considered part of a natural ecosystem cycle. Large forest fires on Earth are usually caused by lightning and can be visible from orbit. Above, in the year 2000, stunned elk avoid a fire sweeping through Montana’s Bitterroot Valley by standing in a river.
