Celestial Observations – 01/02/2022

1230 – Using a 40mm and 30mm eyepiece in a Celestron C90 I observed two sunspots (approximately 3:30). A check of solar data showed a SFI of around 93.

1756 – Using a 10mm eyepiece in a Celestron C90 I observed Jupiter approximately 30 degrees in the sky. Moons IO, Ganymede, and Calisto were visible.

Venus was too low in the horizon to see. Saturn quickly moved out of view. No moon was visible (New Moon).

Today I purchased “The Backyard Astronomer’s Guide” and a 2x Barlow Lens.
