The Sun Online and solar activity. August 25, 2013

Flaring activity is very low. Solar wind speed has decreased to around 400 km/s.* Current geomagnetic conditions are unsettled, which are expected to continue or increase to active levels during the next few hours.

Currently, on the sun’ superficiality we can detect eight active regions with sunspots.
However, astrophysicists from the Royal Observatory of Belgium expected the possible increase of geomagnetic activity in the next few hours.

* The solar wind flows from the outer part of the solar corona. The solar wind – is a stream of charged particles released from the upper atmosphere of the Sun. It mostly consists of electrons and protons.
The solar wind creates the heliosphere, an enormous bubble in the interstellar medium that surrounds the Solar System. Other related phenomena include geomagnetic storms that can knock out power grids on Earth, the aurora (northern and southern lights), and the plasma tails of comets that always point away from the Sun.

Waning Moon online 21 – 22 of August 2013

Waning Moon

Visibility 95-97%

The Moon is the only natural satellite of the Earth and the fifth largest moon in the Solar System.

Visible craters: Langree (Langrenus),  Copernicus (Copernicus), Petavius ​​(Petavius). And amazing lunar maria:

◊ Sea of ​​Serenity (Latin Mare Serenitatis).  The diameter is 700 km. Mare Serenitatis connects with Mare Tranquillitatis to the southeast and borders Mare Vaporum to the southwest. Mare Serenitatis is an example of a mascon, an anomalous gravitational region on the moon.

◊ Sea of ​​Tranquility (Latin Mare Tranquillitatis). The mare material within the basin consists of basalt formed in the intermediate to young age group of the Upper Imbrian epoch. This Mare has a slight bluish tint relative to the rest of the moon and stands out quite well when color is processed and extracted from multiple photographs. The color is likely due to higher metal content in the basaltic soil or rocks.

◊ Sea of Crises (Latin Mare Crisium). Mare Crisium is 555 km (345 mi) in diameter, and 176,000 km2 in area. It has a very flat floor, with a ring of wrinkled ridges toward its outer boundaries. Ghost craters (craters that have largely been buried under deposits of other material), are located to the south.

Sun Online. Solar activity 24-Aug-13

Solar activity 24-Aug-13

Solar activity was very low, featuring only 2 C-class flares (C1.0 and C1.4).
All active regions were quite stable. Solar activity is expected to be low, with a slight chance for C-class flares.
No Earth directed CMEs (Coronal Mass Ejection) were observed.
Solar wind speed currently is around 500 km/s.
Currently, on the sun can be identified nine active regions with sunspots.

Current geomagnetic conditions are unsettled. We expect unsettled to minor storm levels for the next 48 hours, related to the CME arrival, possibly combined with some minor influence of a coronal hole fast speed stream.
Magnetic storm even a small one can provoke headaches, dizziness, high blood pressure problems, heart rhythm disturbances, fatigue, depression.
Be carefull today and take care!
