REMARKS:
I arrived at my observing site before 16:00 (UT). The weather was a little cloudy then. Besides, Perseus hasn’t risen yet. So I waited for more than 1 hour and took some photos of constellations.
The sky became quite clear without cloud after 17:00 (UT). Mars shone brightly in the south. M31, the Double Clusters in Perseus and several other deep sky objects could be seen easily with naked-eye. During my observation, I saw several satellites, including one possible Iridium flare (about -2 mag).
Because I didn’t plot this night, I couldn’t tell meteors from SDA, SIA and NDA apart. Some of the meteors I considered as sporadic ones might come from these three showers.
