# CCD and DSLR maxima of RR Lyrae stars in 2016 and 2017

## TL;DR

This paper reports on the maximum brightness timings of RR Lyrae stars observed in 2016 and 2017, contributing to the GEOS RR Lyr survey's data collection efforts.

## Contribution

It provides new maximum timing data for RR Lyrae stars from 2016-2017, enhancing the observational dataset for this variable star class.

## Key findings

- Maximum timings of RR Lyrae stars were successfully recorded.
- Data contributes to ongoing RR Lyrae variability studies.
- Observations support the GEOS RR Lyr survey objectives.

## Abstract

We present here maximum timings of RR Lyrae stars observed in 2016 and 2017 by VSOLJ member Kenji Hirosawa. The calculation of the time of maximum from the measurements provided by the observer have been made in the frame of the GEOS RR Lyr survey.
