From the February 2020 Celestial Calendar:

2/18 The Moon is 0.8 degree north of Mars, with an occultation occurring in the Azores, the southern portion of Greenland, northern South America, the Caribbean, most of Central America, and North America with the exception of western Canada and Alaska, at 13:00 *

The waning crescent Moon passes less than one degree north of Mars on February 18th.  A short article on the occultation that will occur for much of the continental United States, Canada, and parts of Central America can be found on page 50 of the February 2020 issue of Sky & Telescope.

 

There's an article on the event posted at https://www.skyandte...-february-18th/

The occultation is also discussed at https://www.nasa.gov...p-february-2020 and https://www.skyandte...PB7m2JXNco9Cezw

 

I've included a screen capture (click to enlarge) from Stellarium based on my EST zone and latitude of 40 degrees north location showing Mars prior to the occultation on Turesday morning.

As of now, I'll be clouded out. But I'm hoping the weather shifts so I get a peek at this!

I observed an occultation of Mars in 1999 with a reflector. 

And I highly recommend it to anyone. 

 

I do hope it will be clear for some of you. 

Ireland will not see it happen this time. 

 

Regards from Aubrey.

BTW, Mars will pass between M8 (the Lagoon Nebula) and M20 (the Trifid Nebula) in Sagittarius on Monday morning.

Stellarium also shows the occultation occuring with M8/M20 sandwiching the moon during event, here in AZ. Should be pretty good. About 4:30 am 18th.

I was hoping to see this event, but as usual when there is a significant one time event here it will be cloudy.

The local forecast is also not very promising for that morning.

Thanks for all the info and links, Dave.  I'd love to see this occultation--the geometry isn't always this favorable--but we're forecast for clouds and rain overnight and all day Tuesday.  frown.gif

Took this image of Mars and M18, with the Slooh Wide Field Astrograph, this morning (2-17). Unfortunetly the wind was a bit of a problem. I was hoping to image the pair tonight but the Moon is too close.

I saw Mars disappearing and appearing back. Managed to get some photos too.

First time shot with the celestron's 0.63 reducer (on C5) and I think that cost me some image quality. :-( Either the reducer is faulty or some other problem that made it very hard to focus the moon in my camera. Usually it is very easy!

Oh well! Now I am sleepy and back to work, will post the pictures later.

Nice view of the Mars occultation through thin clouds and city lights.  Used the AP Mak-Cass with an 8mm Radian eyepiece (460x) for the disappearance and a 55mm Plos (67x) for the reappearance.  My wife used an AP130 with a 15mm Panoptic for low power views of both. Mars was only a diffuse blob being only 11 degrees above the horizon on entry.  Last Mars occultation I observed was in 1971 when we did visual timing with a stop watch listening to WWV and sent the observations into IOTA.

Great view here ~4:38 am.  Questar 3.5 with a 16 mm brandon eyepiece. Also a 50 mm Celestron finderscope.  No clouds, just the city lights and sometimes unsteady seeing to battle.

It was clear here in Tucson, but because the moon was low (10 degrees), the disappearance was a little blurry.  The reappearance was very nice.  APM 152ED, TeleVue 12mm Delos for 100x.

I watched through the 10" and took photos with the C5+. It was fun, though a little earlier than I like to get up smile.gif

A pre occultation shot with an old hand held digital Sony camera at a 12mm eyepiece in a 4.25" f/5 homemade Dobsonian scope.
