Radioman reported radar surface contact at the same time I was able to id the lead vessel as Furutaka with the TBT, just before ordering periscope depth (I forgot to write the distance down but I assume it was less than 2000 because of the fog+night conditions, I only obtained "TBT lock" on the ship very lately).
Hope this help.

Good! Thank you! That definitely helps.
