Sunday was a good day. In the morning, I had a nice solar session with my
I have started with doubles at 20:30 with onset of nautical darkness. Then, with onset of astro darkness switched to asteroids. However, some of my target asteroids were behind trees or still too low. So, over the course of the evening I was switching back and forth between doubles and asteroids. But, to keep the report easier to follow I will list all asteroids and all doubles in two sections.
ASTEROIDS
As my list of observed asteroids grows it becomes tougher to log new ones. On one hand, I have to pursue fainter asteroids. On the other, my home sky getting worse year to year, and it is harder to observe faint targets. This session were more misses than hits. Still, I managed to catch four.
For the last few years TV Panoptic 27mm was my main
This is my asteroid catch of the evening, all with Delos 17.3mm (156x).
(165) Loreley – mag 12.9 asteroid in Cancer.
(214) Aschera – mag 12.9 asteroid in Libra. With mean diameter of ~23 km, this is one of the smallest asteroids I have observed.
(470) Kilia – mag 13.0 asteroid in Virgo. Another small asteroid, ~27km in diameter.
(704) Interamnia – mag 13 asteroid in Orion. Interamnia is on the opposite side of the scale from Aschera and Kilia. With mean diameter of ~330km, it is the 5th largest asteroid and accounts for at least 1% of the total mass of the asteroid belt.
