Narrative:
At the top of a thermal spiraling right, I decided a transition toward lake tahoe. After 3 seconds of transition both my student and I saw a yellow and red mass passing under our glider from a 8 O'clock to a 2 O'clock position. No corrective action possible. Supplemental information from acn 334684: aircraft was on a heading for the visual approach to rno descending to 11000 ft. Aircraft went across final just east of minden when he reported a near midair collision -- pilot called it a 'near miss.' no primary target was observed where near midair collision occurred. There were other targets southeast of his position by 5 mi. I was not in contact with any glider.

Title: INSTRUCTOR PLT IN A G103 (GLIDER) RPTS AN NMAC WITH A B73S. THE B73S PASSED 50 FT BELOW THE GLIDER, AND THE GLIDER INSTRUCTOR PLT WAS UNABLE TO TAKE EVASIVE ACTION.
Narrative: AT THE TOP OF A THERMAL SPIRALING R, I DECIDED A TRANSITION TOWARD LAKE TAHOE. AFTER 3 SECONDS OF TRANSITION BOTH MY STUDENT AND I SAW A YELLOW AND RED MASS PASSING UNDER OUR GLIDER FROM A 8 O'CLOCK TO A 2 O'CLOCK POS. NO CORRECTIVE ACTION POSSIBLE. SUPPLEMENTAL INFO FROM ACN 334684: ACFT WAS ON A HEADING FOR THE VISUAL APCH TO RNO DSNDING TO 11000 FT. ACFT WENT ACROSS FINAL JUST E OF MINDEN WHEN HE RPTED A NMAC -- PLT CALLED IT A 'NEAR MISS.' NO PRIMARY TARGET WAS OBSERVED WHERE NMAC OCCURRED. THERE WERE OTHER TARGETS SE OF HIS POS BY 5 MI. I WAS NOT IN CONTACT WITH ANY GLIDER.
