Re: Equinox, Full Moon and Easter

[Steve Lelievre]

Roger, the Easter calculation uses March 21 as the equinox irrespective of
the astronomy.

Equinox, Full Moon and Easter

[Roger]

I always thought Easter Sunday was on the first Sunday after the first full 
moon after the spring equinox. This year at my location, time zone PDST, the 
equinox is at 2:59 pm Wed 20 March 2019. The full moon is about 4 hours later 
at 6:43 pm. Why is this Sunday not Easter and Friday not Good Friday. What 
about the Passover. It is also a month later. I know setting the date of Easter 
was the problem that inspired astronomy but this year the scientific data and 
the religious credo do not seem to agree. 

Where have I been mislead? (other than finding silly girls posing as sundials)

Re: Schmoyer Sunquest

[Ian Maddocks]

Hi gents.
#sundial might seem loosely applied but that yoga pose is called the sundial 
apparently.  I come looking for photos of UK dials to add to the Register but 
have to wade past the yogists and photos of people with their desserts at the 
Sundial restaurant Atlanta.  It's worth it for the number of unknown dials I 
find.
Regards
Ian

Thanks Ian

It looks like the real McCoy, a well crafted well crafted Schmoyer Sunquest.

I had a look at the Instagram link. The #sundial tag seems to be loosely 
applied. What do silly girls in acrobatic poses have to do with sundials?

hi

In case anyone is interested I have just seen a Schmoyer Sunquest pop up on the 
Instagram feed for a Minneapolis antique shop

Claims to be a Schmoyer made in 1960s

Hello, all

When making sundials with pupils of different ages, I was practicing two 
approaches:

1. Joyful: direct marking of hour lines from the shadow at certain moments (for 
7-10 years old). 
2. Scientific: production according to the drawings (geometric construction and 
program calculations for older children).

When going the first way, a stand-alone 
EXEL-program from Ricardo Cernic (  http://www.mysundial.ca/tsp/sun.html ) was 
very useful.  I've failed to find something as convinient for smartphones and 
tablets, and posted a  new Sun calculator on    https://freeright.net . It 
meets my goals, and
may be interesting for someone else.

A few remarks.

1 Accuracy and precision of calculations

VBasic procedures with Meus's algorigths from EXEL-prototype were just 
re-written in PHP-language. So, in general it should be perfect, 
as Ricardo Cernic and Carl Sabanski did a great job while testing original 
source. 
Many thanks to Ricardo, who sent me protective password, and allowed to "pick" 
his code.
All output parameters are rounded to readable and measurable values.
-0.83 degree refraction factor for sunrise/sunset is assumed. All angles are in 
decimal form.
Ephemerides are recalculated in realtime mode every 60 seconds (accompanied by 
a slide show on desktop).

2. Features

- as Geolocation API is used, seting your current coordinates and time zone 
becomes easier;
- annual and daily reports are available in CSV-format. It is possible to 
import it in any spreadsheets program,
steps are 5-10-15-30-60 minutes, or 1-10-15-30 days;
- a layout of simple horizontal sundials can be generated for a given latitude 
(with exception to
near equator ;-);
- although it has nothing with the sundials, you can calculate the dates of 
Easter/Pesah holidays. Calculated 
Georgian-Julian days-shift by Carl Gauss is used.  
 
3. Security

Due to Google-driven recommendations, some browsers do not allow you to use 
Geolocation API with unprotected http-sites.
Just use secure https-connection instead. 
The application is server-based, Java and cookies free, no registration, no 
tracing, no adds.

4. Errors

Inevitable, but will be corrected as they appear. Please, write directly, if 
any occur. 

Congratulations with tomorrow equinox!
