Solar session on september, 15
Posted by anmalo on Monday, September 16, 2013 10:13 AM

Hi all:
On Sunday, I observed in white light the Sun between 10h30m and 10h50m UT. I could check its low activity to be at a solar maximumCrying. I watched one sunspot that was made up of 2 umbrae, inside the same penumbra.Maybe,Its size was similar to Earth's. In addition, this sunspot was very close to solar equator. According to NOAA, its latitude was of 6º S
I took a look around the solar disk trying to find more spot (or,at least, a pore). Only I found one facula, appearing on the southeastern limb. The rest of the solar disk was clear. Someone had decided to use bleach or similar.Smile

I hope  some big spot appears on the Sun on September 29, because that day I have a  public solar observing session, else we'll have to give people carrot juice to distinguish spots.Smile

Regards
Angel

I'm watching the sun on SOHO every few days. Yes, it has become very quiet, in terms of sunspot activity. But I think on the other side there are a few more sun spots, last I saw two or three medium sized ones. Not sure if they will be around this side by September 29th.

The currently quiet Sun has been a topic at http://spaceweather.com/ for the last several days (September 14-16).

Take a look at the SOHO image for Sept. 3, thats a possible view of the sun at that time. It depends on how much these features change between now and then. You will see them come across a few days before the 29th.

The Sun does seem to be a bit uncooperative at the moment.  Perhaps we are entering (or already in) one of the Sun's unstable periods where the rules and predictions are suspended, or at least modified.   Still, I hope the Sun deigns to put on a show for you on the 29th.

Solar activity is on the increase again.  It's thought that the 2013 solar maximum may be double-peaked.
