What is the solar activity like today?
Overall, sun activity remains low, although you wouldn’t think so by looking at today’s sun in extreme ultraviolet with SDO (see image below). There are bright active regions (sunspot groups) and several dark filaments, especially on the southeast part of the sun. July 7, 2022.
Will there be a solar flare tomorrow?
No significant active region flare activity is forecast.
Where are we in the sunspot cycle right now?
Analysis determines we are in Solar Cycle 25 We are now in Solar Cycle 25 with peak sunspot activity expected in 2025, the panel said. Solar Cycle 24 was average in length, at 11 years, and had the 4th-smallest intensity since regular record keeping began with Solar Cycle 1 in 1755.
Is solar activity increasing?
We are currently at a solar minimum, and will therefore see an increase in solar activity between now and 2025. However, even at solar maximum, the energy that the Earth receives from the Sun is only around 0.1 per cent higher than average.
What is going on with the sun?
We’re in a new solar cycle and the Sun is waxing towards “solar maximum” probably in July 2025. Solar maximum is a peak in the Sun’s roughly 11 years solar cycle when the most sunspots are seen. Solar minimum is the trough when the fewest sunspots are observed.
Should I worry about solar flares?
Solar flares sound scary, but they won’t exactly destroy the Earth. The Sun’s occasional eruptions could reach our planet if they are especially powerful, and at that point may cause damage to power grids.
Do solar flares affect your body?
Although eruptions of energy from the sun can damage satellites, power infrastructure and radio communications, they do not harm people.
Where can I find solar flare forecasts for Australia?
Solar flare forecasts are also available through the WMO Information System (search for “solar flare”; requires registration). See the Australian Space Weather Alert System (ASWAS) for a description of the R (radio blackout) scale.
What is the SWS solar cycle prediction based on?
The Bureau of Meteorology SWS solar cycle prediction is now based on the Version 2.0 values. The values in the smoothed 10.7 cm solar flux table are derived from daily 10.7 cm solar flux values adjusted to 1 Astronomical Unit (A.U.). The daily values are averaged to provide monthly mean values which are then smoothed.
Where can I find solar data for the morning and afternoon?
Average 9 am and 3 pm cloud maps showing morning and afternoon total cloud amount. Measurements of thirty minute and daily total solar energy from a small network of specialised ground observation stations are available at a cost recovery charge. Please refer to the summary of available solar data before sending a request.
What were the solar wind conditions on 24 January 2019?
Ambient solar wind conditions were observed on 24 January with a peak speed of 338 km/s. The peak total IMF was 7 nT until 1710 UT when a small step occurred, with the total IMF peaking at 11 nT after that. The north-south IMF (Bz) range was +/-6 nT. Coronal hole effects are expected to produce mildly enhanced solar wind conditions 25-26 January.
