Sunspot

Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere. Sunspots usually appear in pairs, with pair members of opposite magnetic polarity. The number of sunspots varies according to the approximately 11-year solar cycle.

Individual sunspots may endure anywhere from a few days to a few months, but eventually decay. Sunspots expand and contract as they move across the surface of the Sun with a size ranging from 16 kilometers (10 mi) to 160,000 kilometers (100,000 mi) in diameter. The larger variety are visible from Earth without the aid of a telescope. They may travel at relative speeds, or proper motions of a few hundred meters per second when they first emerge.

Indicating intense magnetic activity, sunspots accompany secondary phenomena such as coronal loops (prominences) and reconnection events. Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings. Similar phenomena indirectly observed on stars other than the sun are commonly called starspots and both light and dark spots have been measured.

Sunspots (economics)

In economics, the term sunspots (or sometimes "a sunspot") usually refers to an extrinsic random variable, that is, a random variable that does not affect economic fundamentals (such as endowments, preferences, or technology). Sunspots can also refer to the related concept of extrinsic uncertainty, that is, economic uncertainty that does not come from variation in economic fundamentals. David Cass and Karl Shell coined the term sunspots as a suggestive and less technical way of saying "extrinsic random variable".

Use

The idea that arbitrary changes in expectations might influence the economy, even if they bear no relation to fundamentals, is controversial but has been widespread in many areas of economics. For example, in the words of Arthur C. Pigou,

'Sunspots' have been included in economic models as a way of capturing these 'extrinsic' fluctuations, in fields like asset pricing, financial crises,business cycles, economic growth, and monetary policy.Experimental economics researchers have demonstrated how sunspots could affect economic activity.

Man-in-the-browser

Man-in-the-Browser (MITB, MitB, MIB, MiB), a form of Internet threat related to man-in-the-middle (MITM), is a proxy Trojan horse that infects a web browser by taking advantage of vulnerabilities in browser security to modify web pages, modify transaction content or insert additional transactions, all in a completely covert fashion invisible to both the user and host web application. A MitB attack will be successful irrespective of whether security mechanisms such as SSL/PKI and/or two or three-factor Authentication solutions are in place. A MitB attack may be countered by utilising out-of-band transaction verification, although SMS verification can be defeated by man-in-the-mobile (MitMo) malware infection on the mobile phone. Trojans may be detected and removed by antivirus software with a 23% success rate against Zeus in 2009, and still low rates in 2011. The 2011 report concluded that additional measures on top of antivirus were needed. A related, more simple attack is the boy-in-the-browser (BitB, BITB). The majority of financial service professionals in a survey considered MitB to be the greatest threat to online banking.

Extreme ways are back again
Extreme places i didn't know
I bought everything new again
Everything that i'd owned
I threw it out the windows, came along
Extreme ways i know move apart
The colors of my sea
Perfect color me
Extreme ways that that help me
Help me out at night
Extreme places i had gone
But never seen any light
Dirty basements, dirty noise
Dirty places coming through
Extreme worlds alone
Did you ever like it planned
I would stand in line for this
There's always room in life for this
Oh baby, oh baby
Then it fell apart, fell apart
Oh baby, oh baby
Then it fell apart, it fell apart
Oh baby, oh baby
Then it fell apart, it fell apart
Oh baby, oh baby
Like it always does, always does
Extreme songs that told me
They helped me down every night
I didn't have much to say
I didn't get above the light
I closed my eyes and closed myself
And closed my world and never opened
Up to anything
That could get me along
I had to close down everything
I had to close down my mind
Too many things to cover me
Too much can make me blind
I've seen so much in so many places
So many heartaches, so many faces
So many dirty things
You couldn't believe
I would stand in line for this
It's always good in life for this
Oh baby, oh baby
Then it fell apart, fell apart
Oh baby, oh baby
Then it fell apart, it fell apart
Oh baby, oh baby
Then it fell apart, it fell apart
Oh baby, oh baby

CyprusMail 12 Apr 2025
You’ve got a new brown spot on your face, but is it a freckle or a sunspot? Or perhaps you’ve found a spot on your back that looks like a mole but is flatter than your other ones – is it a mole or a dark freckle?.
