News of different types

Comets 21P/Giacobini-Zinner and 46P/Wirtanen

The recent apparitions of periodic comets 21P/Giacobini-Zinner and 46P/Wirtanen have been intensively monitored.  The analysis and the enclosed plots made by Erik Bryssinck well show the preliminary results on the two objects. Comet 21P displayed a regular curve peaking about 18 days before perihelion in agreement with the 1998 apparition (Lara et al, A&A 399- 2003).



Software and Database upgrade in progress

Good news is going to come.

We have hardly worked, and are still working, on building the NEW Af[rho] measures's Database.
A new Winafrho software version will be soon available with included a function to upload automatically afrho datas to the database on the fly.
As well as updating Winafrho, we are going to adapt the website procedures to match the new database format.

Stay tuned for big news !!!
