I'm new to solar observing and would like to get some feedback on my set up and first two tentative observations
My equipment consist of:
- 6" F/8 Newtonian
- 50X, 75X, and 100X Brandon eyepieces
- Full aperture Baader white light solar filter
- Baader solar continuum eyepiece filter
Last two mornings my observations were:
Date = 06/19/2018, Time = 15:00 UTC, Sky Conditions = Fair/Hazy, Count = 38 (3 clusters and 8 spots @ 75X)
6/20/2018, 14:32 UTC, Clear/good, 51, (3 clusters and 21 spots)
Thanks in advance.
All your equipment looks OK. The magnification may be a little high at 75 X, perhaps reduce that to less than 50 X if you can. If you haven't already, please read the Solar Observing Guide: https://www.aavso.org/solar-observing-guide
When you first login to the SunEntry please make sure your Header information is correct. And welcome to solar observing!!
Here are my observations for those dates:
Don't be surprise about the difference, those groups were changing a lot and you did the estimations 7 hours after mine.
My material is a refractor 102/1000 with a white light glass objective filter. Magnification 50x.
For fun I attach the sketch I did June 20th.
Is there someone from the Solar Obs Section who will attend the Warwick meeting? For reasons that are too complicated to explain here I've got a few questions (concerning the history and future of sun-spot counting in more general terms) that I'd like to discuss with people who are participating in this section.
Apologies for the long delay, I didn't notice that you attached a sketch to your post above. Your drawing is exceptional and i appreciate you sharing .
Your count is way too high for this latest Active Region 2737. There is only 1 group and perhaps 8 to 13 sunspots at most. Not sure what you mean by clusters, but seems like you thinking a 'cluster' is a group. Please look over this Sunspotsandpores.pdf (attached).
Perhaps try to reduce your magnification and eyepiece to around 25 mm.
Hello Steve, welcome to solar observing! I will echo Rodney's recommendation of taking a look at the solar observing manual. Only modest equipment and safe solar filters are necessary for observing the Sun. I use a TeleVue 76mm Apo with a Nagler 7mm Type 6 eyepiece and full aperture white light filter. I hope you will enjoy safe solar viewing!
Sorry Folks, I was just looking through some old post and commenting on Michael's drawing that I missed originally. The sunspot count mentioned in the first post was from 20 June 2018 when I started this thread.
I've appreciated all the advice and suggestions you all have provided and have implemented them in my solar observing program.
FYI From my notes: My last count was on 02 April 2019, 1 group / 6 spots, @50X.
Again apologies for the confusion.
Edit: I did some digging and believe the count made in the original post was for active regions 2713, 2714, 2715. Please correct me if I'm wrong.
