Hello Craig Berry,
The Annic Nova takes 1 to 6 (1D) weeks to recharge the energy accumulators depending on the distance from and spectral type of the star serving as the radiation source.

As much as I love playing the "make ALL the canon consistent!!" game, I think we have to toss Annic Nova if we are to maintain any semblance of sanity in the background. Even if you handwave an explanation (my favorite is the usual dodge that its drive is a one-of-a-kind Ancient artifact), it makes no sense at all that reports of a ship that could jump without refueling didn't trigger an all out, every-ship-committed effort by the Imperium to locate the ship for study.

The Annic Nova article is in JTAS 1 on pp. 17-18. On p. 17 are three reported sights of the Annic Nova. The first sighting was in the Spinward Marches at Heya (0802) jumping out of the system while the scrambled fighters were at extreme range, followed a five week lay over at Kinorb (0602), and the last sighting was a Dentus (0601) an the five Type S Scouts/Couriers scrambled to intercept the ship got a bit of data.
I have not checked out the chunk of space described but in the first two reports they had no data to work with, in the third report the scouts figured out that the unidentified ship is capable of J2. How are you going to search for a ship that is capable of J2?
A ship that has fuel for a one J4 could make a J2 jump enter the system and, not recommended in the rules, could jump out again utilizing fuel for a jump of 1 or 2 parsecs.
Until the party boards the Annic Nova no one has enough information to know that the five week lay over it took 5 weeks to recharge the ship's accumulators to make a jump.
The best that could been done was to alert all the worlds within a J2 radius of the sightings. Of course if the J3 drive gets used there goes the J2 radius of warning.
