23/9 17:00 After the first peak that reached today's high and reported earlier, a new 7.35 Hz Frequency dip that started at 8 UTC caused the Amplitude to rise to Power 31 just before 9. After this movement, the Amplitude has returned to calm values. The Frequency, after having also returned to normal values, began a slow descent accompanied by fluctuations of the Quality.

23/9 08:30 After several days in which it has constantly remained below the base value, the Frequency has returned to normal values from 19 UTC yesterday and started more marked oscillations from 1 UTC. From the same hour there were also movements of the Quality which reached 7 at 2 UTC. Amplitude did not have movements until about 4 UTC when a dive to 7.50 Hz of the Frequency pushed the Amplitude to Power 35. This Amplitude movement lasted just under 60 minutes.

22/9 17:00 Today's activity lasted 12 hours, from 1 to 12 UTC with the most intense part from 5 to 9 UTC, a period in which the largest oscillations in Frequency and the maximum peaks in Amplitude and Quality occurred. From 11 UTC, the frequency rised to 7.60 Hz with moderate oscillations and this brought the other parameters to calm values.

22/9 08:30 As in the previous days, even today the frequency has remained constantly low. Further lowering and large swings started at 1 UTC and this was accompanied by movements in both Amplitude and Quality. The Frequency reached the minimum value of 7.37 Hz at 5 UTC and from this moment onward even wider variations are occurring. Amplitude recorded Power 24 just after 5 UTC, Power 41 just before 7 and Power 42 at 8 UTC.

21/9 17:00 The Frequency continued to remain low, especially in the last 6 hours, and both the Amplitude and the Quality continued with slight movements which did not reach high values.

21/9 10:30 As can be seen from the new Frequency graph, the maximum value in the y-axis range is 7.83 Hz and has only been reached twice in the last three days. This did not cause significant movements but only variations that today had their maximum value at Power 14 reached several times around 5 and again at 9 UTC.

20/9 17:00 No changes, we are still in the same calm condition with the Frequency oscillating now below 7.70 Hz.

20/9 10:30 Just after yesterday's last movement at Power 37, from 9 UTC, began a period of calm which lasted almost 24 hours, it has been interrupted by light isolated movements of short duration at Power 11 at 2:30 UTC and Power 14 at 8 UTC. For most of the past 24 hours the Frequency has continued to fluctuate around 7.70 Hz.

19/9 17:00 The Frequency returned to oscillate at 7.70 Hz from 6 UTC, after the strong variations that brought the Amplitude to the maximum of Power 64. A new wider oscillation at 9 UTC led to a second isolated peak at Power 37. After this isolated movement of short duration the situation calmed down again.

19/9 09:30 From 17 UTC yesterday the Frequency remained constantly below 7.70 Hz, from 1 UTC it started a drop down to 7.33 Hz, reached at 5 then quickly returned to above 7.70 few minutes later. The Amplitude had the first movements above Power 10 parallel to the Frequency movements at 1 UTC, when it just began the last plunge to 7.33 Hz the Amplitude peaked at Power 64 [3:45 UTC]. One more Amplitude move reached Power 37 at the time of this update.

18/9 17:00 The Frequency is oscillatin on the 7.60 threshold, the rest is calm.

18/9 10:30 A powerful new isolated peak reached Power 57 shortly after 9 UTC, at the same time that Quality reached 8, the movement laste about 30 minutes.

18/9 09:00 Compared to the previous two days, today's Frequency graph shows how this has made a "step" upwards passing from oscillations around 7.60 Hz to those around 7.70 Hz. Some larger variations seem to have given the start to movements of the Amplitude that at 7:30 UTC with an isolated peak of short duration reached Power 40. Interestingly, the maximum values of the Frequency, around 8 Hz between 19 and 20 UTC yesterday, coincided exactly with two remarkable peaks of the Quality at 12.70.

17/9 17:00 The wide oscillations of the Frequency are continuing, the Amplitude has returned to values around Power 10.

17/9 15:30 In its surge, the Amplitude reached Power 71 at 15 UTC, this movement started at 13 UTC simultaneously with more marked oscillations of the Frequency.

17/9 15:00 Wide variations in Frequency accompanied a sharp Amplitude spike initially at Power 47 at 14:30 with a forther increase at Power 55 a7 14:45 UTC.

17/9 14:30 The Frequency decreased and started to fluctuate around 7.60 Hz from 10 UTC, this has led to more significant movements even if the maximum values are unchanged.

17/9 12:30 Even today a series of slight Amplitude movements that started around 1 UTC when the Frequency had large oscillations around 7.70 Hz. The sequence is still in progress and so far the maximum value reached has been Power 16 at 6:30 UTC.

16/9 17:00 A series of steadily decreasing Amplitude movements, after the maximum value of Power 16, seem to have ended the activity. The Frequency for the whole day has fluctuated around 7.60 Hz, today it reached the base value once, only momentarily at 6 UTC; at the time of this update it continues to be low.

16/9 07:00 Still slight isolated movements that temporarily interrupt the calm condition, an oscillation of the Frequency starting at 2 UTC pushed the Amplitude to Power 16 at 3:30 UTC. This was the only significant movement in the past 16 hours.

15/9 17:00 Not much to report, the calm condition continues with some slight Amplitude movement and moderate Frequency swings.

15/9 10:30 The drop in Frequency started yesterday at 19 UTC and the minimum of 7.39 Hz was reached around midnight UTC, this movement of the Frequency was coupled with a series of variations in the Amplitude that reached Power 13 just before 24 UTC yesterday and Power 11 at 1:30 UTC this morning during the rising frequency phase. At the time of this update, the Frequency fluctuates slightly below the base value of 7.83 Hz and the Amplitude reached again Power 11.

14/9 17:00 The slight instability continues, mostly due to the movements of the Frequency, but there are no significant movements.
