日本国家天文台建造了两台新望远镜，即太阳耀斑望远镜和10厘米新日冕望远镜。在三鹰建造了太阳耀斑望远镜，以便同时观测光球速度场、矢量磁场以及活动区的Hα和连续图像。整个系统将于一九九一年完成。10厘米的新日冕仪是为了精确测量几个波长的日冕强度而开发的，已经在Norikura太阳观测站运行了一年。目前，在连续光下，太阳盘面强度的精度达到了10-6，但测光精度仍有待进一步提高。
Two new telescopes were built at the National Astronomical Observatory of Japan, i.e. the Solar Flare Telescope and the 10-cm New Coronagraph. The Solar Flare Telescope was constructed at Mitaka to make observations of photospheric velocity fields, vector magnetic fields, and Hα and continuum images of active regions simultaneously. The whole system will be completed in 1991. The 10-cm new coronagraph, which was developed to make precise measurements of the coronal intensity in several wavelengths, has already been in operation for one year at the Norikura Solar Observatory. At present the accuracy of about 10-6 of the solar disk intensity is achieved in continuum light, but further improvement in the photometric accuracy remains to be done.
