The Seven Sisters Conjunction

Scientists at the North London research institute THoF believe we are currently witnessing what is possibly the first ever occurrence of a phenomenon known as the Seven Sisters Conjunction. This is defined as the moment when the two bodies AFC and THFC appear at the extreme opposite ends of their seasonal trajectories. Researchers refer to these extremes as positions 1 and 20.

The Seven Sisters Conjunction is a special instance of the more general phenomenon known as the Seven Sisters Differential. This is calculated through the formula: (x) AFC :: (y) THFC. At the present time the values of x and y are 1 and 20 respectively (please see Table 1 for details).

This gives the result: 1 AFC :: 20 THFC, so the Differential is currently +19 (see note 1), and the two bodies are indeed in a state of Conjunction.

The Seven Sisters Conjunction is by its very nature temporary. It could last as little as a few minutes, depending on what are known as KO times, or it could be a matter of days, weeks, or even months. The two bodies could slip out of conjunction, and then slip back in again later. However, there is a limit: Conjunction cannot carry through from one season to the next. Were THFC to remain in position 20 for the remainder of the present season, it would find itself relocated to a secondary universe or ‘Division’, and the calculations would have to be done on a different basis (see note 2).

A further point to note is that, were a situation of Conjunction, or near Conjunction, to persist, this could well affect the timing of the annual celebration of St Totteringham’s Day. Mathematically this cannot occur before the mid-point of the season, but observers will no doubt be watching with interest.

We will try to keep track of events as they unfold here.

Notes
1) You will notice that the Differential is expressed here as a positive value - this is normal. Negative values (ie, where the value for THFC is lower than that for AFC) have been known to occur, but they are atypical and are usually of brief duration.

2) Were THFC to be relocated to a secondary Division, the Differential would have to be expressed in the form: 1.x AFC :: 2.y THFC, and the value of the Differential would depend on the maximum values of these coefficients - for several years now (1) has had a max of 20, and (2) a max of 24.

As an illustration, in the event of a hypothetical situation of 1.1 AFC :: 2.24 THFC, the Differential would be +43 (1::44), and the situation would be classed as a Secondary Conjunction. This is regarded as highly unlikely to happen in the short term, but as the THoF researchers say, “you never know”.
