There are currently 9 sunspot groups visible on the solar surface. NOAA 2104, 2108 and 2109 are the most prominent regions, but do not have magnetic delta’s. This may change for NOAA 2108 and 2109, as these groups have shown a gradual increase in sunspot area over the last 24 hours. Four C-class flares were observed. NOAA 2108 produced 3 of them, including the largest event being a C4.2 flare peaking at 14:39UT (4 July).
C-class flares are expected, with a chance on an M-class flare from NOAA 2104, 2108 and 2109.
Solar wind speed declined from 330 to 290 km/s, with Bz varying between -1 and +3 nT. Geomagnetic condions were quiet and are expected to remain so.

The spiral arms of bright, active galaxy M106 sprawl through this remarkable multiwavelength portrait, composed of image data from radio to X-rays, across the electromagnetic spectrum. Also known as NGC 4258, M106 can be found toward the northern constellation Canes Venatici. The well-measured distance to M106 is 23.5 million light-years, making this cosmic scene about 60,000 light-years across. Typical in grand spiral galaxies, dark dust lanes, youthful star clusters, and star forming regions trace spiral arms that converge on a bright nucleus. But this composite highlights two anomalous arms in radio (purple) and X-ray (blue) that seem to arise in the central region of M106, evidence of energetic jets of material blasting into the galaxy’s disk. The jets are likely powered by matter falling into a massive central black hole.

M63 (also known as NGC 5055, or the Sunflower Galaxy) is a spiral galaxy in the constellation Canes Venatici consisting of a central disc surrounded by many short spiral arm segments. M63 is part of the M51 Group, a group of galaxies that also includes M51 (the ‘Whirlpool Galaxy’). M63 was discovered by Pierre Méchain on June 14, 1779. The galaxy was then listed by Charles Messier as object 63 in theMessier Catalogue.
In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.
In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.
