I am back home from Philadelphia. I didn't get any observing done there. There was nowhere where I could see the western horizon to try for the first crescent Moon or the δ Cap occultation and the day when I tried to go out to do a sunspot count a visitor to the booth told me it was snowing. Now I am working to learn enough Morse code before the end of the month to pass a 5 word per minute test and upgrade my amateur radio license so may not get much observing in until next month.
The Sun moved over into Capricornus while I was away and, since I wasn't doing any observing, I didn't realize it.

There is one spot visible on the leading limb of the Sun with some plage on its limbward side.

I can still see two spots although the group is getting close to the foreshortening zone. The p spot is the latger. I didn’t see any penumbra.

I have been getting ready for the next full Moon and wondered of there was any correlation between the phase of the Moon and its altitude when it transits.
I went to Planetarium and looked up the transit time on each day of the next three lunations and plotted the altitude against the date.
I don't see any relationship. It appears that they length of the altitude cycle is shorter (26 days) than that of a lunation (29.5 days).

The sky looked dark but there were no stars visible anywhere but to the SE. I am assuming there must have been a deck of stratus up there but I couldn’t see it.

It was kind of strange out tonight. The forecasts said it would be somewhat cloudy with poor visibility. On arriving home after the monthly PHP meeting (a programming language for writing dynamic Web pages where the HTML displayed to the user is written on the fly when the user calls them, which I don't do although I attend the meetings each month) I started looking for stars as soon as I left the subway station. I couldn’t see anything anywhere until I got to the block one block south and parallel to my block were I saw one “star” that I assumed from its brightness and size was probably Saturn. When I got into my block I stopped to look out to the SE where that “star” was and saw another dimmer star beneath it and knew I was seeing Saturn and Regulus. Moving around a bit to get different parts of the sky in the hole between the buildings I saw Procyon, Sirius, and Orion’s shoulders and belt. But there was nothing visible in any other part of the sky.
