Now that I have actually looked at the start times a little closer for 2019, it doesn't look like many good observing nights this year...   :-(

At least in the east of North America. I have noted this before, that you can have long, dry spells at a given location. I think this is one reason the effect is not more widely known.

Dana,

 

Thanks for all your help last year in explaining lunar X and V. While nothing worked out in 2018, last night the weather cleared for about 10-15 minutes just in time for me 

to observe both with my Questar 3 1/2.

 

My next chance will be in April, so hopefully, with better weather, I'll have more time and be able to break out one of my heavy hitters to watch the progression across the crater rims.

The notes above show Lunar X is tomorrow at the following time:

 

03/13/2019    1526UT

 

I see its already happened...  I could never figure out the UTC Conversions.

 

We just changed to Daylight savings time in Calif. What time would this be tomorrow here in Calif, anyone know the conversion? Would that be 8:26am? If so, on what date?

 

thanks for any help.

 

...Ralph

It would be 8:26am for ya'll. I may try to capture this during my lunch at school tomorrow with the orange tube C5. Lunch luckily lines up tomorrow for this event!

As you guys have probably already figured out, the Moon is not above the horizon during the event for the United Stated this March.  The possible exception is on the East Coast, where you can sort of catch the tail end of the event as the Moon is rising above the horizon near mid-day, but this is not ideal.  On the East Coast, the Moon will only be about 10 degrees above the horizon, during the middle of the day, as the event is nearing its conclusion.

This is the worst year in my memory for observing the Lunar X after sunset....
