Okie-Tex Star Party: 2018 repeat

Posted on

Saturday morning September 16th and the 40th annual Okie-Tex Star party is officially over. And it was similar to the star party in 2018 unfortunately.

The Oklahoma City astronomy club has been hosting a annual star party for forty years. For the past twenty five years it has been held in western Oklahoma by the little town of Kenton (population 25?). This years event started September 8th, the earliest in September that I can remember attending. Early September is usually hot in the Oklahoma panhandle and this year days before the official start there was record high heat in the area. Friday’s high temperature was around 95 F at the camp.

The first night was clear and the sight of the Milky Way was awesome. The sight of thousands of stars in the night sky is the reason I drive out every year. I took full advantage of the night staying up until 4am Saturday morning. The sky from midnight until moon rise was pretty good but I did not see the Gegenschein.

Unfortunately that first night was the last good night I saw there. Saturday was another hot day in the mid 90s. Saturday evening we were just missed by a nasty storm front. Very light rain at the camp with golf ball sized hail reported in Boise City. I believe it as the storm clouds were a interesting bluish color. The passing storm front caused serious winds at the camp site. Unbelievably my own campsite was hit with a downdraft that knocked my scope over. Yes, for the third year in a row I was hit with a dust devil or heavy wind gust. Fortunately I suffered only minor damage and I certainly plan to be in a different part of the field next time I camp there!

Sunday was rain off and on, heavy at times. About an inch fell at a nearby CoCoRaHS monitoring site. In fact Camp Billy Joe got more rain in 24 hours than my home in Kansas has gotten for past weeks. Its seriously dry, level 2 drought at my home, so I certainly could have used the rain there. Monday was cloudy and overcast with occasional sprinkles. At least it cooled off with morning low around 60 degrees F. The forecast for the rest of the star party looked poor so I decided to leave early. Its not particularly fun to tent camp in a damp environment with no chance of clear skies. Tuesday morning I finished packing up my still wet tent and headed back home.

While I got to see a blazing Milky Way in a dark sky at the start of Okie-Tex I never got to spend the time I wanted under the stars. The weather pattern was terrible for the star party this year – just like 2018. Unfortunate and out of anyone’s control but disappointing after having spent weeks preparing for the trip.

Clouds for Perseids

Posted on

This year the Perseid meteor shower timing was very good with its usual peak time occurring after midnight for my timezone. The moon would be nearing new and not much of a factor.

Unfortunately the weather pattern turned out to be cloudy. Below is the NWS satellite image just after midnight on the 13th. This would have been the peak time Sunday morning.

From the IMO reports I note the Perseid shower was about its usual strenght. So I did not miss anthing special this year. The next big meteor shower will be the Geminids in December and like the Perseids it has very good timing this year.

Firefly Peak 2023

Posted on

Every year in my backyard the approach of summer brings a magical show. The night becomes more and more active with light emitting bugs. Most of us call them fireflies, or lightning bugs. I really enjoy sitting out and watching them. Over the past week I feel like it has reached peak firefly time around my place this week.

The build up to this years show has been a bit odd to me. Around the last new Moon in June I would see more fireflies before it was truly dark than later in the night. Around the start of Nautical Twilight there would be large numbers of fireflies hovering closer to the ground in the backyard. Like they have just woke up and are getting ready for the night. A few hours later when its really dark I would see far less fireflies lighting up the sky.

Were the fireflies moving off to a secret meeting place? When I first noticed this pattern I started looking around in neighbor fields and the wooded areas. They had about the same amount of flashing bugs as I did. I never did solve this mystery but this past week I have been seeing more fireflies at night. Usually concentrated in my woods. This leads me to think I’m seeing the highest number right now, the peak of their activity this year.

Bit Tired of Hyperbole

Posted on

This year my annoyance with astronomy exaggerations started off with the years first meteor shower, the Quadrantids (QUA). I ran across an article on LiveScience that starts out:

How to watch the Quadrantids – one of the best meteor showers all year – on Jan. 2 and 3

I’m going to need a citation for that, except there isn’t one because its not true. One could say its potentially one of the strongest meteor showers but its certainly not among the best. Not this year with a nearly full moon out on the peak night. I get that the headline was derived from the linked NASA article but maybe the author should consult more resources like the IMO article when writing. At least the author later writes “short-but-spectacular show” because that is true and one of the big issues with QUA is it is typically only highly active for a few hours.

My big issue with this article is it sets up unrealistic expectations for readers. It says the shower is great but fails to qualify why it could be and more importantly fails to highlight the difficulties of viewing it. Unlike the IMO article I linked above. Maybe a better headline would have been: “How to watch the Quadrantids – first meteor shower of the year”. Because this years Quadrantids were weak.

About the same time as the Quadrantids I started see headlines like “Dazzling Green Comet”, “Rare Comet Approaching Earth”, “Closest in 50,000 years”, etc. Oh boy, you know this isn’t going to go well for the general public. Talk about setting up unrealistic expectations! Seems the more hype the less the event lives up to it and unfortunately that was true again for the general public (1) .

Comet 2022/E3 ZTF is an interesting comet from the perspective of its age and orbit. As 2022 progressed it became clear in the amateur astronomy community the comet might, just maybe, reach naked eye visible. If you were outside the city in dark skies. But even that was a bit pointless when the comet was closest to Earth the moon was out for most all of the night.

I did have some clear skies the night ZTF was closest to Earth and I can say that the average person would never see this with their naked eyes. I certainly did not and I knew exactly where to look. It was easily visible in binoculars but very washed out with the moonlight. That is it was just a faint smudge. With a telescope the comets core was well defined but the rest of the detail was lost in a moon lite sky.

Around the 10th of February comet ZTF was approaching Mars and fortunately my skies were clearing as well. Over the next few nights I imaged ZTF by Mars. Examining the images on screen as they were downloading I was struck by wonderful paring of a this green comet with a reddish orange Mars against a dark sky.

This may have been the best time to share the comet with the general public. To have a live digital feed for people to see (usually called EAA – Electronically Assisted Astronomy). By itself the comet would have looked nice on a screen but when it was near Mars the sight was very pretty.

Notes

Tau-Herculids: Observing Report

Posted on

In 1995 The comet 73P/Schwassmann-Wachmann suddenly increased in brightness and broke up. This event was unexpected and due to its orbit being close to Earth the possibility of a future encounter with its debris could result in a meteor shower. Joe Rao wrote one such paper back in 2020 and many of us meteor observers were interested in the conclusion we could see something in 2022. As the time drew closer many more articles like this one in EarthSky further fueled the anticipation that something might happen.

Fast forward to Saturday May 28th and I was facing a problem: the weather forecast looked poor for eastern Kansas. During the week before I was carefully watching the weather and the Clear Sky Chart(s) for my area. By Sunday it was clear the models were predicting accurately and my area would be cloudy. Monday the 30th was the latest and last model run I would check on the Clear Sky Charts. South-central Kansas looked good with no clouds forecast through 1AM. Fortunately I had been researching a destination and had a spot picked out.

Late Monday afternoon I headed down to Kingman Kansas, about 45 miles west of Wichita. Outside that town to the west is Kingman State Fishing Lake and Wildlife Area which has its own Clear Sky Chart. It took about 3 1/2 hours driving to end up at my chosen spot. Thirty minutes later I was setup and waiting to observer the Tau Herculid (TAH) meteor shower. It could be just one meteor or it could be much more.

Waiting for darkness. Two cameras and SQM meter ready to go.

As true darkness neared, before I was officially observing, I saw three TAH meteors. This was a good sign! Any other year that maybe what one would see all night out of this practically unknown meteor shower. Once astronomical darkness had started I was officially observing. The night sky was reasonably good with a lot of moisture and atmospheric extinction near the horizon. My overhead SQM readings averaged 6.4 visual limiting magnitude, certainly a decent location despite the light domes from nearby towns.

The meteor shower was good but there was not an epic outburst of meteors that could have been possible (but was unlikely). For the Tau Herculid meteor shower this was an exceptionally active night, an outburst. And that was the point of this adventure, on this night Earth passed through a stream of debris from a very recent comet breakup. The model predictions that we would encounter some material from the 1995 break up turned out to be correct.

My actual observing report is filed here at the IMO. I recorded a total of 32 TAH meteors that night. Its possible I under counted the TAH meteors as I was a bit uncertain in some cases as the radiant area seemed pretty large. Meteors most often had short trails but I was surprised how bright many were compared to what I expected. During my night out I had two cameras running and based on @JAtanackov’s suggestion I ran one camera with a narrower FOV lens than I normally use. This 50mm/f1.4 lens was stopped down to 1.8 and captured a number of Tau Herculid meteors that likely would not have shown up very well using my wider angle lens. A quick review of the 700+ images captured on that camera shows one very bright meteor with an interesting sequence of images which I will post later.

Lunar Eclipse: May 15th

Posted on

Sunday the 15th was a wild weather day as a storm blew through my area in the morning knocking out power for myself and a lot of people in the metro KC area. However, as forecast, the sky cleared later for the lunar eclipse. This is the last ‘complete’ total lunar eclipse visible at my location for several years to come (1) so I was anxious to watch it. For me this was an exceptionally nice eclipse and hopefully I have a few pictures to post later. Pictures are nice but truly experiencing a total lunar eclipse is where its at.

What made this total Lunar eclipse particularly great was how dark the moon got. Probably the darkest I have ever seen it. I am not alone in thinking that as others commented on the darkness as well. It truly was a spectacle with the dark orange-red moon floating among the stars. This is something I feel requires darker skies to fully appreciate.

For me one of the most interesting and exciting characteristics of a total lunar eclipse is experiencing the changing moonlight as the hour from first contact (U1) to eclipse (U2). At first as the Earth’s shadow takes a small bite out of the moon its not significant but each passing minute slowly reduces the moonlight until its gone. Even then the moon is going through a transition from the dark of eclipse start to maximum darkness at greatest eclipse and back to slowly brightening again as it heads towards the eclipse end.

Certainly one doesn’t have to sit outside watching the entire time. Lunar eclipses are fairly slow so one can enjoy the view for awhile and take a break. However just coming out once to see the moon at maximum eclipse isn’t watching an eclipse. Its just taking a peek, you lose the magic of going from a bright full moon illuminating the landscape to the eerie scene of a dark moon. Something that doesn’t happen regularly and only during a total lunar eclipse.

RMS Station Online

Posted on

Composite image of meteors captured last night at my station, center meteor looks like a nice one!

Over the past weeks I’ve been finishing up a long running project to build a station to be part of the Global Meteor Network (GMN). Its been an interesting project that I will be posting more about soon. The short summary is the GMN is a network of inexpensive cameras that collect and report data for use in meteor research. Up until today I’ve been finalizing the configuration and testing its operation but I’ve not been a contributing station.

Tonight it will watch the sky and collect data as an official part of the GMN.
