８月はすっきり晴れた日は少なかったが、撮影はそれなりだった。
お盆は夜に晴れても夕方は曇り、撮影できなかった日が多々あった。
特にトピックも無く、日本で見える空に限れば、新星発見もなかった。
◆ASASSN-17hx
ゆっくり減光。デジカメは赤に強いため眼視光度より明るく写りまだ９等台。
ただ、極大時にはその差が小さく、増減光時には大きく１等程度の差。
眼視に近いという3色分解後のG画像でもやはり明るく、デジカメ測光に
疑問が残る。ただ、同一器材での継続撮影、測光結果には意味がある。
ASASSN-17ｈｘ＝たて座新星 ＊撮影時刻は画像外が正しい
香川県の藤川さんによって発見されたワイ新星。撮影エリア外で明るさも
デジカメ撮影には少し辛い光度。
ASAS-3で調べた結果、過去にも増光しているようだ。
