Time In Fractional Day As Used In Astronomy (e.g., MPC)– Excel Spreadsheet For Conversion (Both Ways).

What my Excel spreadsheet looks like. It is converting ‘.67810’ into a time format we can understand.


Time that comets are discovered are specified in this ‘fractional day’ format.

So, for example, time when C/2020 F3 (NEOWISE) was discovered per the ‘Minor Planet Center’ (MPC).

The .67810 used above is FROM this example.

The Excel FORMULAS used in the Spreadsheet.

So, now you can quickly & easily create your own Spreadsheet.

I had trouble deciphering this time format. I had to seek help from a professional astronomer — Jeff Mangum. [Thank YOU, Jeff.]

I then dashed off a quick Excel for MY use. Then I decided I should create a version that I can SHARE.

Yes, of course, I could make it a download — but many would be leary of downloading it. So, intead, I am sharing the simple Excel formulas you will need to create your own. Yes, it can be made simpler. SMILE. I just wanted to show YOU the steps so you could see where I was going. SMILE. Plus, I am, at 67, not the hotshot programmer I was when I was in my 20s. SMILE.

It is crazy that there is still confusion as to the sensor size and format. Of course it will be a Micro Four-Thirds. That is what the sensor format is on the Panasonic Lumix LX100 and Panasonic will not mess with that.

The big issue is whether the LX200, in contrast to the LX100, will ever use the full-size of the sensor.

Interesting that they have brought forward the announcement date. They probably don’t want the Pentax K-70 full disclosure on July 15, 2016 to steal too much thunder given that both cameras will be in the same price range.
