Well, just had my first ever hostile encounter in Aurora, and I'm not entirely sure what happened.
Discovered the System of Epsilon Eridani several years ago, noted 3 unknown wrecks orbitting the second body, so I sent a frigate squadron for a quick sweep of the system, they moved through the system without noting anything unusual and so returned to their regular station.
Comes time when the jump gate has been completed that the second body is my next target for colonisation. (At this point I still haven't completed any surveys of the system, my survey efforts are behind where I'd like to be thanks to a black hole incident and several other factors. ) I set up a colony on the planet, and order one of the cargo squadrons to start hauling in some infrastructure and a tracking station. Assigned an administrator and then went to check on available ground forces to use for the initial garrison.
It's at this point the line "Abandoned Installations -
(Unknown race, xenologist team required)" catches my eye. OK, the garrison chosen moves up from being a garrison brigade to a spare Mobile Infantry brigade, a xeno team is formed planetside. (I kind of feel bad about this, especially seeing as I have a shuttle in service whose sole purpose is to ferry around my geo team).
Fast forward to the Troop ship arriving planetside and conducting unloading operations, 3 hours into the task I suddenly get a new hostile contact message! New Thermal Contact! Strength 5 Active Sensor S0 7/R84. I'm not entirely sure what that means but I didn't stick around to find out, unloading is cancelled and the Troopship plus the still inbound cargo squadron are ordered to retreat to the other side of the jump gate.
Fleet training is cancelled and 3 task forces are hastily assembled out of my currently incomplete fleet. A Frigate squadron holds station over Earth to act as a reserve and an emergency last ditch defence if things go terribly wrong, A second Frigate squadron pickets the jump gate Sol side. My last Frigate squadron, and the recently completed and still half trained CL/DD squadron proceed to make the jump and picket the planet. About 1. 5b Kms out, I remember to go into the combat summary and set up my PD fire controls. I reach the planet without hazard, and decide to switch on shields and active sensors, to see if I can flush anything out.
4 hours later (and 2 hours after the shields finish charging), new contact!

Hostile Missile Contact (x4)15th November 2028 10:00:01, Epsilon Eridani,
Hood - Fire Control S04 24-12000 H50 targeting Missile Salvo #8919 at 0k km: Base Chance to hit: 104% (Fire Control To Hit: 100% Modified by Crew Grade: 104%)15th November 2028 10:00:01, Epsilon Eridani,
(x4) Hood: Single TCS 24 Gauss Cannon R2-100 TurretFire Control To Hit: 100% Modified by Crew Grade: 104% hit the target and destroyed an enemy missile. I had no indication where the missiles came from, but considering my sensors are currently lit up (after reading the forums I do include res 0 active sensors) and I detected the missiles at 0 kms, I assume their origin is planetside.
And now, another 15 days have passed, and. . . . nothing.
No new missile attacks, no contacts on active, nothing on passives. Nothing.
The troopship is currently on its way back to the still picketed planet to see wether boots on the ground will reveal anything. But the single wave of 4 missiles out of the blue has me scratching my head a little.
