Narrative:

I am a fairly new fpl with 6 months radar time. I was working the radar position at my facility on 10/91. I was on position approximately 1 hour with a relieving controller waiting to get into position. A lot has been on my mind at home due to a relative that moved into my house from out of state. The relative has caused some friction between myself and my spouse. An mlt aircraft called southeast of my airport at 85 wanting to pick up an IFR clearance into cos airport. He was VFR and climbed to 105, I idented him. I gave him the clearance and called den center to put in a departure message, start track and hand the aircraft off to me. (Though the aircraft was in my airspace the computer recognized him as zdu control). I was also tagging up an military helicopter inbound from the northwest for practice approachs. I had the mlt on a vector to keep him east of the airport and away from airport traffic. (He was now IFR at 100). I don't recall how many but I had several VFR aircraft inbound to the airport. An additional mlt Y called southeast of my facility wanting VFR flight following to cos airport. This aircraft called at 1000 ft AGL (approximately 5700 MSL) and I missed the altitude. I suppose because the first mlt called at 85 also. I tagged him up idented him and was waiting to give the relief briefing. The VFR mlt Y was idented approximately 10 mi outside the air traffic area. Giving the briefing I didn't pay much attention to the VFR mlt Y. I was given a departure strip in cpr X heading 020 degree climbing to 70 off runway 8L. During the briefing I wanted to let the relieving controller know that the IFR mlt needed to be coordinated with cos approach as he was on a heading and not the airway. I finished the briefing, everything appeared to be in order. I was anxious for a break to think about problems not related to work. I unplugged and about 1 min later the relieving controller asked me about the VFR mlt Y. I explained he was VFR to cos. I then heard the controller tell cpr X to maintain visual separation from mlt Y. Apparently mlt Y and cpr X had gotten close. I never saw cpr X and I did not see how close the aircraft got to each other. Mlt Y was VFR and had entered the air traffic area. I did not realize this and did not coordination with local. Unfortunately this happened during a briefing, a critical point while on position. If I would have realized mlt Y was that low, I would have told him to remain outside the air traffic area or coordinated. Supplemental information from acn 192962. Cpr X after takeoff at 5700 ft encountered mlt Y 1/2-3/4 mi at 12 O'clock at same altitude. Expedited climb. Tower did not mention additional traffic when issuing IFR clearance and takeoff clearance. After contacting departure control, departure controller did not mention mlt Y until I brought it to their attention. I asked departure controller if they coordination the mlt Y with the tower. They said no. Then the controller changed and I was handed off to cos approach control.

Narrative: I AM A FAIRLY NEW FPL WITH 6 MONTHS RADAR TIME. I WAS WORKING THE RADAR POS AT MY FACILITY ON 10/91. I WAS ON POS APPROX 1 HR WITH A RELIEVING CTLR WAITING TO GET INTO POS. A LOT HAS BEEN ON MY MIND AT HOME DUE TO A RELATIVE THAT MOVED INTO MY HOUSE FROM OUT OF STATE. THE RELATIVE HAS CAUSED SOME FRICTION BTWN MYSELF AND MY SPOUSE. AN MLT ACFT CALLED SE OF MY ARPT AT 85 WANTING TO PICK UP AN IFR CLRNC INTO COS ARPT. HE WAS VFR AND CLBED TO 105, I IDENTED HIM. I GAVE HIM THE CLRNC AND CALLED DEN CENTER TO PUT IN A DEP MESSAGE, START TRACK AND HAND THE ACFT OFF TO ME. (THOUGH THE ACFT WAS IN MY AIRSPACE THE COMPUTER RECOGNIZED HIM AS ZDU CTL). I WAS ALSO TAGGING UP AN MIL HELI INBOUND FROM THE NW FOR PRACTICE APCHS. I HAD THE MLT ON A VECTOR TO KEEP HIM E OF THE ARPT AND AWAY FROM ARPT TFC. (HE WAS NOW IFR AT 100). I DON'T RECALL HOW MANY BUT I HAD SEVERAL VFR ACFT INBOUND TO THE ARPT. AN ADDITIONAL MLT Y CALLED SE OF MY FACILITY WANTING VFR FLT FOLLOWING TO COS ARPT. THIS ACFT CALLED AT 1000 FT AGL (APPROX 5700 MSL) AND I MISSED THE ALT. I SUPPOSE BECAUSE THE FIRST MLT CALLED AT 85 ALSO. I TAGGED HIM UP IDENTED HIM AND WAS WAITING TO GIVE THE RELIEF BRIEFING. THE VFR MLT Y WAS IDENTED APPROX 10 MI OUTSIDE THE ATA. GIVING THE BRIEFING I DIDN'T PAY MUCH ATTN TO THE VFR MLT Y. I WAS GIVEN A DEP STRIP IN CPR X HDG 020 DEG CLBING TO 70 OFF RWY 8L. DURING THE BRIEFING I WANTED TO LET THE RELIEVING CTLR KNOW THAT THE IFR MLT NEEDED TO BE COORDINATED WITH COS APCH AS HE WAS ON A HDG AND NOT THE AIRWAY. I FINISHED THE BRIEFING, EVERYTHING APPEARED TO BE IN ORDER. I WAS ANXIOUS FOR A BREAK TO THINK ABOUT PROBLEMS NOT RELATED TO WORK. I UNPLUGGED AND ABOUT 1 MIN LATER THE RELIEVING CTLR ASKED ME ABOUT THE VFR MLT Y. I EXPLAINED HE WAS VFR TO COS. I THEN HEARD THE CTLR TELL CPR X TO MAINTAIN VISUAL SEPARATION FROM MLT Y. APPARENTLY MLT Y AND CPR X HAD GOTTEN CLOSE. I NEVER SAW CPR X AND I DID NOT SEE HOW CLOSE THE ACFT GOT TO EACH OTHER. MLT Y WAS VFR AND HAD ENTERED THE ATA. I DID NOT REALIZE THIS AND DID NOT COORD WITH LCL. UNFORTUNATELY THIS HAPPENED DURING A BRIEFING, A CRITICAL POINT WHILE ON POS. IF I WOULD HAVE REALIZED MLT Y WAS THAT LOW, I WOULD HAVE TOLD HIM TO REMAIN OUTSIDE THE ATA OR COORDINATED. SUPPLEMENTAL INFO FROM ACN 192962. CPR X AFTER TKOF AT 5700 FT ENCOUNTERED MLT Y 1/2-3/4 MI AT 12 O'CLOCK AT SAME ALT. EXPEDITED CLB. TWR DID NOT MENTION ADDITIONAL TFC WHEN ISSUING IFR CLRNC AND TKOF CLRNC. AFTER CONTACTING DEP CTL, DEP CTLR DID NOT MENTION MLT Y UNTIL I BROUGHT IT TO THEIR ATTN. I ASKED DEP CTLR IF THEY COORD THE MLT Y WITH THE TWR. THEY SAID NO. THEN THE CTLR CHANGED AND I WAS HANDED OFF TO COS APCH CTL.
