SUMMARY OF PROPOSAL 41078 PROFESSOR HIROSHI TSUNEMI FACULTY OF SCIENCE, OSAKA UNIVERSITY OSAKA JAPAN 560 TOYONAKA 1-1, MACHIKANEYAMA E-mail: TSUNEMI@ESS.SCI.OSAKA-U.AC.JP Tel: 06-850-5477 Fax: 06-850-5539 Medium: 2.5GB8MM Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION Title: OBSERVATION OF G69.7+1.0 AND G7.7-3.7 DETECTED BY ROSAT Abstract: We propose to observe two SNRs that are newly discovered with Rosat. They are G69.7+1.0 and G7.7-3.7. G69.7+1.0 shows an extended structure parallel to the galactic plane suggesting the hot bubble prevailing in the galaxy. G7.7-3.7 shows a shell structure with asymmetric X-ray brightness. Since they are dim in radio, they have not been observed before the Rosat era. They may form a new type of SNR groups.
