Thee Years of Sunspot Counts

It's now three years since I decided to make a point of doing sunspot counts as often as possible (I say "now", I'm actually a few days late make a note of this).

While weather, and other things, do often get in the way, I've managed to log 378 observations so far. The sunspot graphs are coming along pretty nice too (even if they are a bit flat due to the solar minimum).

The sunspot/active area observation list is starting to get pretty long now and, at some point, I might have to think about reworking it so it pages or something. On the other hand the active area timeline is doing fine (and it shows rather nicely just how quiet things have been of late).

I hope things start to pick up this year. It would be nice to see some significant solar activity again.

Eclipse Observing Log

I've now uploaded my observing log from today's eclipse. There's a handful of photographs in there too. Nothing too special, just captures of the view as seen via the Solarscope.

I'll probably get around to uploading some more elsewhere at some point. I'll post here when I do.

Quiet Sun Again?

This evening I've been catching up with my observing logs. Recently all I've been managing to do in terms of observing is sunspot counts and I've got a nasty habit when I do them. Given that I do the counts during the day (dur!) I tend to pop into the garden with the solarscope, do a quick count (or not so quick if things look interesting — I'll even photograph the sunspots if I think it'll be interesting enough), and then pop back into the office and write the key details on a scrap of paper and place it under my monitor.

The problem with this is I tend to let them pile up. Eventually I crack and write them up in my observing logbook and then type up the XML log file that gets turned into the online log.

This really is one nasty habit I should break.

The thing that I did notice when sorting out these latest logs this evening is that I've not seen a sunspot since 2008-03-31 (the last one seen and recorded being part of active area 988). While this isn't quite so long a time as late last year it does seem rather quiet again, at least in terms of the days I've been able to observe and what I can see with my modest equipment.

It's all making my sunspot graphs look rather bare.

Two Years of Sunspot Counts

A little earlier I was typing up some recent solar observation reports and I realised that it's now over two years since I started observing the sun as often as possible and keeping a log of sunspot counts.

The weather seems to have been against me lately. Over the past few months I've not managed to log many observations (see March this year for example: only 6 counts recorded) and that's kind of frustrating.

Still, the graphs of solar activity seem to be coming along nicely. Even though there's a fair bit of data missing due to days when I couldn't observe there does seem to be a general hint of the recent solar minimum.

Another Lubitel Star Trail

Further to my last attempt at some star trails with my Lomo Lubitel 166B I've now received a scan of the developed film of one I did I did during a session on 2008-02-09.

This time I was using Ilford HP5+ 400. Conditions were less than ideal, the sky was rather hazy for the whole observing session and everything got rather damp pretty quickly (hence the reason there's only one trail for the whole session). However, despite all of this, it's turned out better than I thought it would.

Thanks once again go to Tim Haynes for processing and scanning the film.

Lubitel Star Trails

Last week I managed to finish off the film in my Lomo Lubitel 166B which contained some star trails I did during an observing session on 2008-01-05. After some developing and scanning by a friend (thanks Tim!) I finally got to see the results.

And they're not too bad either:

Obviously those thumbnails don't do them justice so click on the images or visit the whole set to see the large versions.

Quiet Sun

I've just been catching up on my observing logs and I've just noticed how long it is since I last saw a sunspot.

So far this month I've not seen a single thing on the Sun. Neither did I see anything during the whole of October. Almost all of September was quiet too with the last time I saw a sunspot being September 1^st.

You can see from my graphs that this is quite a prolonged quiet spell.

From what I've read solar minimum now seems to be predicted for March next year. Now, okay, I know these things can be ±6 months or so, but it has got me wondering if I'm in for a very quiet winter when it comes to solar observing.

In other news: I managed to get another look at comet Holmes last night.

You could fill a book... Part III

My short session observing comet Holmes a couple of evenings ago was also another little milestone for me. I finally filled my third log book.

This third book has taken quite a long time to fill. I filled the second one just over a year ago and it took less than a year from me filling the first one.

The main reason for this is that observing has been quite slow this year. While I've done a fair bit of solar observing, evening/night observing sessions have been few and far between. When I got out to observe comet Holmes back on Monday that was the first non-solar session since May!

The reasons are many and varied, but most revolve around weather, some illness and, now and again, a lack of motivation. Something "special" in the sky is always a good motivator and the summer months were totally devoid of anything to observe that was "special" (yes, Jupiter was about, but was so low that you generally couldn't see it from my garden).

Thankfully Holmes has given me that taste again, got me back into that habit.

It was good to have a 'scope out again last night and I think I've finally got that bug back again.

Battlestar Galactica

I adore the new take on Battlestar Galactica. No kidding, I think it's one of the best, if not the best, SciFi TV series ever made.

Really, it's not just good, it's very good. Amazingly good. So good I don't know how to actually say how good it is.

In other words, I quite like it.

It's the start of a new month. Often, at the start of a new month, when I look at the monthly stats for my websites, I'll find forums out there who are hot linking to images that I host. This annoys me (mostly because the person who has done this is, in effect, "stealing" bandwidth) and I generally go and do something about it. I do, however, try and make a point of seeing what's going on first.

Now you're wondering what this has to do with BSG. Well, last night, I was checking the stats for my astronomy site and I saw some hits from the forums on SciFi.com (before now I don't think I knew they had any, but it makes sense). Thinking that it might be someone hot-linking I went to have a look.

I found that the links came from this thread. Seems that a bunch of people are geeking out over where the colonial fleet are "currently" located. Someone had even gone to the trouble of trying and find a map or two that relates to a chart that is seen in one of the episodes. And this is where the two things link up: Where do they go to get their chart? Here! :-D

Of course, within the universe of the show, there are massive problems with that. As someone in the thread points out:

This makes finding where they are even trickier... Unless the colonies were in OUR SOLAR SYSTEM, there's no way that they could possibly have the same star maps...unless the prop department just grabbed a bunch of star charts (which since they were two dimensional ground perspective maps would be virtually useless in interstellar navigation...) and told the actor to "point there"... Which once again worries me that the writers have no idea where they are...

(which had me laughing out loud for a number of reasons — props? They use props!?! On a TV show!?!?! <g>).

So, yeah, I got a bit of a kick out of that. A bunch of people geeking out over the finer points of a SciFi TV show (which I totally get, I totally get the geeking out thing) and they've done so while referring to something on one of my sites.

In my little geeky world I find that cool. ;-)

Randomness

I just had a rather silly idea, and it took no time to implement.

I was thinking that I've got a lot of observing logs now and, to a large degree, I can generally find the one I want (often via the log index). But it might also be fun to have a facility that selects a random logs.

So that's what I did: view a random observing log.

Accidental stereogram

Not exactly astronomy, but it does relate to one of my telescopes...

Over the weekend I was taking some new photographs of my two 'scopes to replace those on the tools page of my site (the ones that had been there had been taken with mobile phones and were of terrible quality). While reviewing the shots yesterday I noticed that two of them appeared to be taken from almost exactly the same spot and at exactly the same height.

In other words, I appeared to have accidentally created a stereogram. I then placed them side by side in one image and got this result:

If you're the sort of person who can go cross-eyed without any trouble you should be able to see the 3D effect. Click on the image for a bigger version.

A quiet month on the Sun

Going on my records, and keeping in mind the limitations of my equipment, March was a very quiet month for visible solar activity. I managed 20 sunspot counts last month and only saw a sunspot for the first two days of the count. From what I can tell that's the least active month I've observed since I decided to do regular counts starting March last year.

Lunar Eclipse 2007-03-03 - Log now up

I've now uploaded my observing log of the total lunar eclipse.

Logs by comet

Now that I've observed a handful of comets I've got around to adding another way of getting at my logs: by comet.

There aren't that many there at the moment. Let's hope this situation improves this year.

Daylight graphs

I've updated the my sky section of my main site to include a couple of daylight graphs. The first one graphs the rise and set positions of the Sun for the current day:

The second graphs sunrise/sunset times and total hours daylight for my location:


And the reason I added them? Well, no good reason really. They are sort of useful for a quick glance but the main reason I added them is because I fancied a quick bit of hacking (and also because I've been playing with compass-a-like graphs on my weather station site).

A bit more documentation

Given that last weekend's sessions introduced a new type of observing to my logs I felt the need to add a new markup item to my logging system. While doing that I realised that I had no definitive list of all the forms of markup that could be used in the notes for a session or an observation.

So, this morning, I created the list in the (still incomplete) documentation for the file format I use. I've also created a page for each type of markup; each page gives a brief description of the purpose of the markup, the syntax of the markup and also gives an example or two of the markup in use.

I'm glad I finally got around to doing this. From now on I won't need to go looking at my source code or old logs to remind myself how a specific markup item works.

More time stats

After adding the time stats to my stats page earlier to day I realised that I now had most of the tools in place to figure out which part of the day was most "popular" in my logs. I decided that it called for a nice little graph:

From this I deduce I'm not the sort of person who likes to observe during the early hours of the morning. ;)

Time stats

This morning I made a quick addition to the code that manages my observing logs and added some code that extracts the elapsed times for all my sessions. Using this I've been able to add a new section to my stats page that lists some time-based values.

As of now, since 2005-04-16, I've spent 93 hours doing something related to observing. On average I've spent about ½ hour per session. My shortest session is 1 minute long and my longest is 252 minutes long (although the the longest session is a little misleading because there was a break of about 1 hour during it).
