Since you have an IMC, the training requirements are:
5 hours night flying of which:
(1) at least 3 hours dual instruction including at least 1 hour night navigation
(2) 5 take-offs and 5 landings as PIC.
(3) 1 hour solo flying.
In at least one instance take-off and landing should be separated by a complete departure from, and rejoining of, the aerodrome traffic pattern.
A 'night' rating allows you to fly during:
the time between half-an-hour after sunset and half-an-hour before sunrise, sunset and sunrise being determined at surface level.
Hope this helps.
