Full Moon Bike Ride

 The Moon was a little less than two hours past full when i set out on my bike at 6am on Saturday morning.  It looked great hanging there in the West, as I pedaled NW to Bopec, here on Bonaire.  The sky brightens very quickly here in the tropics.

I lost sight of the moon when i headed East to Rincon, but there were lots of birds chowing down on Shimarukus to keep me company.





March Mars Madness

 Mars is on the move. During the next week or so, it will drift between the Pleiades star cluster and the "horns of the bull." (what we call the Hyades cluster in Taurus) Mars is bright orange in color, as is Aldebaran, which forms one of the pointy ends of the horns of the bull. Now that they moon is waning, you should be able to spot the Pleiades overhead in the evening sky. The horns of the bull need a slightly darker location.

 Interestingly enough, i noticed that Mars will be in pretty much the same spot in the sky, relative to the Hyades and the Pleiades, as it was back on Feb. 25, 2006 when I snapped a picture of them.


Above, you can see the shot from 2006 as well as a computer simulation of what you will see on March 8. The simulation is how it will look on Bonaire. Other locations will be slightly different, but close enough that you'll be able to identify the Pleiades, Mars and Aldebaran. Now that i look at it again, March 7 might even be closer to what i saw in 2006.

Jan 28 Sunset - Moonrise

 The Moon was full at 3:16 on Thursday afternoon, here on Bonaire. So Thursday evening was perfect for a Sunset/Moonrise excursion. The Sun set at 6:33 and the Moon rose at 6:39. There were some low clouds in the East so we didn't see the Moon rise up off of the horizon, but it was fun to watch none the less. Here are a few pictures. Click on them to see the whole images.

Wednesday Night Uranus update

 The sky is quite clear here on Bonaire tonight (Wed.) and the mud frogs are singing again after last night's rain.

When one is facing to the West, Mars is easy to spot to the upper right of the moon. Uranus is easy to spot (in binoculars) to the left of Mars. I'd say that Uranus is about a third as far away from Mars as the Moon is, more or less. There is a star to the lower right of Mars, that's not Uranus. Uranus has a distinctive pale robin egg blue coloration.

I'm not going to try taking a picture because the moon glare will drown out the planets, especially Uranus. (probably more because I'm feeling lazy)

Moon, Mars, and Uranus on the 20th

 The Moon will be quite near Mars Wednesday night. Makes it easy to find Mars in the sky. Mars will be to the Northeast of the Moon. As a special treat, Uranus will be to the Southeast of Mars. I'd say that the distance between Mars and Uranus will be about 1/5 the distance between Mars and the Moon.

We've seen Uranus with the naked eye in the past, but you'll need binoculars to spot it with the Moon nearby. On Thursday night, the Moon will have moved away, and Uranus will be more or less due South of Mars, at least as seen here on Bonaire.

TWR TX Site

 I drove out to the TWR transmitter site today to do some work on the computers. When i got there i noticed that it was raining in town, which made the towers and TX hall pop nicely. So i grabbed my trusty i-Phone 6s and snapped away. Gotta love always having a camera in one's pocket.

Double Rainbow

 We have rain off and on every day, with sun in between.  I guess you could call it rainbow season.  We had a nice double rainbow on the morning of the 19th. Just got around to pulling it off of the camera this evening.


 

Jupiter and Saturn on Tuesday

 Here's what Jupiter and Saturn looked like Tuesday evening, more or less. They were a lot closer together on Monday. You'll probably need to look at this full size to split the planets, located in the conveniently placed notch in the tree.


 

Monday Rainbow

 I kept my telescope set up all week with a barbecue grill cover on it for rain protection. That way i could be good to go as soon as the Sun set each night. Last night had patches of clear sky with periodic rain clouds passing by. As soon as the sun got low enough, i took the covers off of the scope so that it could cool off. But i also ate my supper (veggie burgers) outside so that i could zoom over and cover it if a rain cloud came by. Sure enough, a cloud came along and dumped rain for maybe 10 minutes. In this picture you can see the covered scope in the foreground, and a nice rainbow as the rain approached our back yard. Check out the "grass" too. I'm mowing it every about other week.

SAturn and Jupiter Monday

 There were some rain clouds passing through, but we were able to observe Jupiter and Saturn with our naked eye. Saturn is more or less exactly to the right of Jupiter. Tomorrow, it will be to the lower right of Jupiter.

Saturn and Jupiter Sunday

 Jupiter and Saturn are very close together Sunday evening. I think it will be hard to separate them with the naked eye on Monday. This photo is the same scale as the ones from Friday and Saturday.

Saturn and Jupiter Saturday

It is pretty clear tonight. Jupiter and Saturn a bit closer. This picture is the same scale as the one from last night. If you look at it full size, you can just tell that Saturn is Saturn. I might have to shoot video and stack the frames to get a clearer view. Which i might or might not do... If you look at it full size you can (barely) see some of Jupiter's moons too.


 

Saturn and Jupiter closer on Friday

 Saturn and Jupiter were closer together Friday evening, duh. I increased the magnification some, probably to the level i'll keep it at for the next three days. This way it will be easy to see how much closer the planets get each night. These two photos are at the same scale. You can see that less of the Moon fits in the frame. The planets are low in the sky so there is atmospheric refraction visible when i look at them full size. There is a red fringe on one side of the planet and a green/blue fringe on the other side of the planet.

Saturn and Jupiter getting Closer

 Jupiter and Saturn are closing in on each other. They'll be closest Monday evening. They are already close enough to fit in the frame of a picture shot through my telescope. These two pictures are the same scale. It looks like Jupiter and Saturn about the same distance apart as the diameter of the Moon. If it stays clear I'm going to try collimating the scope to see if i can get rid of some coma that was very visible when I looked at the moons of Jupiter at 100% size. Or it may just be the result of the optics being on Bonaire for many years.

Thursday Time Lapse

 

In addition to starry nights, the clear skies here on Bonaire right now provided us a great green flash this evening. Here is a time-lapse made from the pictures i took at the TWR TX site on Thursday evening with a 24m lens. It shows more sky than the one i did on Friday with the 40mm lens.
As Orion's belt goes above the top of the towers, you can see the star Sirius coming up at the bottom of the right most tower. Procyon comes up between the two left towers towards the end of the clip.
 

Friday night time lapse.

 I haven't processed the time-lapse pictures i took at the TX site with a 24mm lens on Thursday night yet. I went back out on Friday and shot a sequence with a 40mm lens. There were more clouds on Friday, but one can still see Orion rise up between the towers. The belt and the sword are pretty easy to spot in the middle of the frame. You'll probably be able to see the stars better if you view it full size.

December Night Sky Wonders

 

December has some good star gazing opportunities. The sky here on Bonaire usually has good transparency when it is not bucketing down rain. Dec. 13/14 is the Geminid meteor shower and the new moon on the 14th. Dec. 21/22 is the Ursid meteor shower. They are best after midnight and will also not have much moon to contend with. I’ve found that the December meteors are the best ones of the year here. Or maybe we’re just out at night more in Dec….
Jupiter and Saturn are getting noticeably closer together in the evening sky. Be sure to watch them from night to night. They will be so close on the evening of Dec 21, that the naked eye might not be able to separate them. I sure hope it is clear here that night.
And, last but not least, there will be a total solar eclipse visible in South Argentina and South Chile on the 14th. Bonaire is too far north to see any of the eclipse, but it should still be pretty good in Montevideo, Uruguay, for our TWR partner there, I would think.
Here's a shot of the rainbow from last Monday.
 

Starry Nights

 It was quite clear Wednesday and Thursday evening, so on Thursday, I zoomed out to the TWR transmitter site to try to do a time lapse of Orion rising behind the antenna towers. I've got some 586 images to combine using LRTimelapse, which I'll try to get to over the weekend. Here is a shot from when i was setting up. I hadn't dialed in the focus yet and I was triggering the camera with the shutter button, instead of the intervalometer. But i like the colors in the sky during the "blue hour." The sky looked dark to the naked eye but a 10 sec. exposure lightened things up a lot. The Pleiades star cluster is at the upper left of the frame. Moving down and to the right, a little more than half way to the top of the nearest tower, you can see Taurus, which we call the "horns of the bull." Orion is still mostly below the horizon in the middle of the frame.

Rainy Days

 We returned to Bonaire on October 31.  It's that rainy time of the year here on Bonaire. Had about 1.6" the morning after we got here. Had 2.2+ inches on Friday. There is no place for the water to go, so lots of roads get covered over with water. That's fun unless you are on a bicycle or scooter. One can't see the potholes under the water.

It rained so hard during church this am that we couldn't hear the pastor. At least one person started listening to the Facebook Live feed on their phone. One could hear the pastor fine on that.

These shots are from in front of our house in Hato.



Note that some people have their boats strategically placed by the road in case it REALLY floods.

Moon Planets June 7-9

The Moon, Jupiter and Saturn are close together in the southern sky.

They make a nice line Sunday night/ Monday morning. 
And they will make a fairly small triangle Monday night/Tuesday morning.
(We spotted the moon closing in on the planets at about 3am on Sunday morning.) 

If you are on Bonaire, you should be able to spot them by 11pm. In more northern points like here in New Jersey, it would be some time around or after midnight.
