  • Saturn (1 mag) – High in the SE sky in the early morning. Rings are very thin and difficult to see.
  • Uranus (5.8 mag) – Located below the Pleiades, in conjunction with Venus this week (distance <3Β°).
  • Neptune (7.9 mag) – Very close to Saturn, appearing as a faint dot between them. A 6.3 mag star above them forms a helpful triangle for identification.

β˜€οΈ Solar Activity

  • A large active region near the center of the disk could bring change.
  • Earth is currently at its farthest from the Sun – a great time to photograph the Sun and compare with images from early January.
