We have analyzed 42 research papers regarding on the solar astronomy written by North Korea scientists to investigate the current status of astronomical activities in North Korea. The papers are surveyed from the ‘Bulletin of Astronomy’, the ‘Physics’, the ‘Bulletin of Academy of Science’, and the ‘Natural Science’ in North Korea, and SCI journals. In addition, we refer to the presentation material announced in the 2015 IAU by director of Pyongyang Astronomical Observatory (PAO) and the 2013 OAD/IAU reports. We have analyzed the papers statistically according to three criteria such as research subject, research field, and research members. The main research subjects are the sunspot (28%), observation system (21%), and space environments (19%). The research fields are distributed with data analysis (50%), numerical method (29%), and instrument development (21%). There have been 25 and 9 researchers in the solar astronomy and space environment, respectively since 1995. North Korea’s solar research activities were also investigated in three area: instrument, solar physics, and international research linkage. PAO has operated two of sunspot telescope and solar horizontal telescope for spectroscopy and polarimetry, but there is no specific information on solar radio telescopes. North Korea has cooperated in solar research with Europe and China. We expect that the results of this study will be used as useful resource in supporting astronomical cooperation between South and North Korea in the future.

We have investigated the North Korean astronomical articles published in five media such as the Rodong Sinmun (노동신문), Minju Choson (민주조선), Tongil Sinbo (통일신보), Munhak Sinmun (문학신 문), and Choson Sinbo (조선신보) for 15 years from 2005 to 2019. The astronomical articles were classified by subject to study the astronomical activity in North Korea. We have examined the perceptions of astronomy in North Korean society through the temporal variation of astronomical articles according to four subjects. As a result, we have found that there are many articles in the subject of Historical Astronomy and Astronomical News in the media. In the era of Kim Jong-un, the articles on the Historical Astronomy decreased while the Astronomy news tended to increase. We have also summarized the specific issues and topics including the change of the standard meridian, launch of satellites, astronomical news, and so forth. The North Korean astronomical article is a valuable resource to examine the current status of North Korea's astronomy and astronomical education. We expect the results of this study to be a useful resource in preparing for inter-Korean astronomical cooperation.
