| Jupiter and Mars in Conjunction (Aug. 14, 2024) |
|
Jupiter and Mars in Conjunction Jupiter and Mars meet each other in a conjunction on August 14 morning, when this image was taken from the Crni Vrh Observatory. This is a single 2-sec exposure, obtained on 2024 Aug. 14 at 2h37UT with 150 mm, f/6 Maksutov-Cassegrain telescope and Canon 700D camera. The angular distance between the two planets was about 24 arc minutes. Both planets are overexposed, so that the Galilean moons of Juper are clearly visible. From left to right are: Ganymede, Europa, Io and Callisto. Copyright © 2024 by H. Mikuz, Crni Vrh Observatory.

| Aurora over the Crni Vrh Observatory (May 10-11, 2024) |
|
An incredible show of the aurora borealis over this part of Europe. Since I've been observing, I don't remember anything like this.
The storm raged through the night in 3 rounds, with the heaviest around midnight. Sun's huge Active Region 3664, produced a surface
explosion that sent a burst of electrons, protons, and more massive charged nuclei into the Solar System. On May 10, that coronal
mass ejection impacted the Earth and triggered auroras unusually far from Earth north and south poles.

| Bright supernova exploded in galaxy M101 (May 21, 2023) |
|
Supernova SN 2023ixf was discovered
by the Japanese supernova hunter Koichi Itagawa on 2023 May 19.7 UT, when the object
was at magnitude 14.9. As of May 21st, when a series of images were taken at �rni Vrh Observatory, it had raised to
about magnitude 11. Spectra indicate that SN 2023ixf is a Type II supernova � the catastrophic destruction of an
aging supergiant star. The object is located 227.7" east and 134.1" south of the galaxy's center at RA 14h 03m 38.6s Dec. +54o 18' 42". M101 lies approximately 21 million light-years away, making this one of the closest supernovae visible in recent years. The last supernova observed in M101 was SN 2011fe, discovered in August 2011 as the Type Ia object, reaching a peak magnitude of 9.9.

| High sunspot activity during the current Solar Cycle 25 (Jan. 20, 2023) |
|
Sunspot activity, 2023 Jan. 18 An interesting Solar activity has been observed during the past days, particularly there is increased number of sunspot groups, with huge sunspot AR 3190 (below and left of center), that is about five times the diameter of Earth and is currently visible also with naked eye, using the solar filter glasses. This image was taken in the morning of 2023 January 18, by Jure Skvarc from La Palma, Canary Islands, with Skywatcher Skymax 127 mm, f/12 telescope and ZWO ASI6200MM CMOS camera. Processed with Autostakkert by stacking the 40 best images. Sun elevation about 23 degrees. Copyright © 2023 by Jure Skvarc.

| Nova Her 2021 = V1674 Her = TCP J18573095+1653396 (June 14, 2021) |
Nova Her 2021 = V1674 Her was initially discovered on 2021 Jun 12.537 UT by Seiji Ueda
(TCP J18573095+1653396),
(CBET 4976), though data from the All-Sky Automated Survey for Supernovae (ASAS-SN) revealed an earlier detection, on June 12.1903 UT (ATel #14710). Munari, Valisa and
Dallaporta spectroscopically classified the new source as a nova close to naked-eye brightness (ATel #14704), while Wagner et al.
(ATel #14746) determined it to be a neon nova.
