Solar conditions have remained steady and just at the quake driving threshold, making for difficult forecasting conditions.
A slow buildup could be underway.

Major winter cold has arrived in Europe during the period.

2 March.
Banda Sea 5.9 3.20pm
Papua New Guinea Highland 5.6 4.01pm
Eruption Kadovar.
This forecast had some merit, extracting clear results from low activity quake periods is difficult.
Quakes were moderate during the period, the Banda Sea 5.9 was a good result from the outlook for late quakes.
Data is limited on the extent of the Kadovar eruption, the volcano has been spewing ash continuously for weeks.
