Faculae but no Sunspot


Observation of the Sun today. Some observers mentioned a small sunspot but I could not observe this. At the limb some minor faculae which I could see both with solarfilm and H-Alpha.

Lunar X and Lunar V during daylight


Lunar X and Lunar V are both optical features on the Moon. Both the letter "X" and "V" can be observed for a few hours before first quarter and near the terminator. It can be seen due to the effect of sunlight and shadows of the rim of different mooncraters. 
Today I took some time to find both Lunar X and Lunar V. According the literature the phenomenon could be seen on May 29, 2020 UT13-15h (Lunar X) and UT15-17h (Lunar V).
This is still during daytime and a challenge with all the sunlight around. But is a good learning for the upcoming (June 17) lunar occultation of Venus.





After sunset I took again some pictures of the moon and found out that Lunar V and even Lunar X was visible.
