We’re fascinated by everything related to pollen, so when Rob McNaught, a retired astronomer from Coonabarabran in inland New South Wales, emailed us about pollen coronas, we were immediately interested. And if you’ve never heard of pollen coronas, don’t worry—you’re not alone! We hadn’t either.

Last week we looked at how things were progressing at the mid-way point of the Victorian grass pollen season in Melbourne and Geelong. This week, we’ll review the season across regional Victoria (and even into southern NSW).
