Spent most of this evening observing objects in the RASC IWLOP. Some of the objects were also included in the RASC ETM(T) observing program as well.
Sketch from IWLOP #053: Rima Ariadaeus
Julius Caesar was viewed with the 10” Meade SCT at x250 magnification at 10:40 PM. Could see the E-SE wall was eroded or non-existent. It looked like the floor was filled/flat but wasn’t sure. Will require another look.
Hipparchus was viewed at 11:52 PM.
It had smooth floors except for the two ghost craters and craters X and N, the latter being slightly off-centre. It also looked like there was an opening in the NW towards Sinus Medii.
The crater Horrocks was inside the crater in the N-NE and had a dark floor in shadow; Halley looked to have impacted/affected the SE rim.
