A new nova, PNV J18205200-2822100, discovered on October 25th, has now broken the unaided eye brightness threshold of magnitude 6.0, with the latest report from New Zealand of 5.4. ( due to the report on November 8th)
PNV J18205200-2822100 is in the teapot of Sagittarius between Kaus Borealis (lambda Sagittarii and Kaus Media (delta Sagittarii). Sagittarius is sinking in the southwestern sky right after dusk, affording only a very narrow window from mid-northern latitudes (Southern hemisphere is much better). But theres still time to snatch a view of this amazing stellar explosion.
Tonight (Nov.16th), i go back to the world heritage site: Sukhothai in Thailand (17° N) to have a challenge. Venus, the evening star is my first guide. then the spout of the Sagittarius Teapot. As effected by the light pollution from nearby town, i can’t see it with unaided eye. But in the image, compare with nearby HIP 90012, i think the Magnitude is ≈ 6.0.
For the foreground, Wat Mahathat in Sukhothai was founded by Sri Indraditya, between 1292 and 1347 as the main temple of the city as well as the ancient Sukhothai Kingdom. The design based on Mandala, representing the universe with main principal stupa.Some basic explanation for the main stupa. It represents the mythical Mount Meru, center of the universe, which is the heavenly abode build by the God Indra to enshrine relics of the Buddha. The surrounding stupas represent mountain ranges around Mount Meru, and the moat symbolizes the cosmic ocean of infinity.
